Coprophagy in Dogs (eating feces)
.
General Information:
Many dogs develop the unpleasant habit of eating feces.  In some animals, it becomes almost compulsive behavior.  These pets eat not only their own feces, but also those of any other animal.
Several theories have attempted to explain this behavior.  Among possible causes are boredom, too much confinement, lack of certain enzymes in the digestive system, vitamin and mineral deficiencies, and neuroses.
.
Coprophagy usually does little harm except transmission of intestinal parasites and fecal bacteria which may cause tonsillitis or intestinal upset.
.
In some pets, nothing seems to stop this behavior.  However, here are a few suggestions that may help:
1.  Remove the feces from the premises daily.  Prevent access to cat litter boxes.
2.  Do not confine your dog to an area where it has bowel movements.
3.  Provide regular exercise for your pet.
4.  One or more laboratory stool examinations may be required to rule out hidden causes.
5.  Provide your veterinarian with an accurate description of the pet’s current, including snacks.
.
Notify your veterinarian if any of the following occur:

Feeding Adult Cats
General Information:
Because cats tend to develop very rigid eating habits, your adult cat’s dietary preferences are likely to be influenced by how much you have fed it during its growth and development.  To prevent "addiction" to one or two food items that may be detrimental to your pet’s health in later years, provide some variety in its diet.  Variety, however, should be provided in the form of various balanced cat foods, not by the addition of table foods.
.
The dietary needs of cats are different from those of dogs, and dog food does not supply the nutrients cats need.  Sever health problems can occur in cats fed dog food.  Also, fish and milk are not the natural foods of cats and do not provide an adequate diet when fed exclusively.
.
Several commercial cat foods are available that provide a complete and balanced diet for cats.  Your veterinarian can recommend some of these and advise you if any supplementation is necessary to meet the needs of your particular cat.
.
Cats require much higher levels of protein in their diet than do dogs.  Unfortunately, protein is the single most expensive ingredient in cat foods.  Consequently, bargain-brand or cheap cat foods contain low-grade, poorly digestible protein.  For your cats good health, avoid the cheaper brands of cat foods.
Special diets are available for specific health needs.  One will be recommended when required.  Water must be available at all times and should be changed at least once daily.
.
How Much?
In general, you can feed your cat according to the manufacturer’s directions, but under certain circumstances the directions should be modified.  The amount will vary according to age, activity, reproductive status, and general health.  On the average a relatively active, non pregnant, non lactating, 8 pound adult cat requires about 30 calories per pound of body weight daily.
.
Different foods vary in their caloric content, but you can use the following general rules:
   Dry cat foods            300 calories per cup
   Semi-moist foods      125 calories per packet
   Canned foods           200 calories per 6.5 ounce can
.
The doctor can help you determine the exact calories contained in a specific brand.
.
Example: an 8 pound active adult cat with no special needs requires 30 calories per pound per day.  You are feeding dry cat food.  The total calories it needs are 8 X 30 = 240 calories.  Therefore, you should feed 240/300 = 4/5 cup of dry food.
.


.
Feeding Adult Dogs
General Information:
Many commercial dog foods are available to adequately nourish the average adult dog.  A good general rule is to avoid the cheapest brands.  Even though cheap foods may have the proper ingredients listed on the label, they may not contain high quality, usable protein.
.
Factors to consider when choosing a diet for your pet include your dog’s age, activity, breed, and temperament.  Also, special diets are needed during pregnancy and disease.  Prescription diets are available for pets with cardiac, renal, allergic, nutritional, skin, and intestinal diseases.
.
Variety is not essential in your dog’s diet.
.
For unenthusiastic eaters, offer a small amount of food, wait 10 minutes, and remove the uneaten portion.  Allow nothing but water until the next regular mealtime.  Repeat this 10 minute routine even if your pet eats nothing for several days.  Your pet will learn that it must eat when food is provided or go hungry.  Do not allow uneaten food to remain available after 10 minutes, and don’t supplement your dog’s diet with table scraps.
.
How Much?
In general, you can feed your dog according to the manufacturer’s directions, but under certain circumstances the amounts should be modified.  Your veterinarian will advise you of your pet’s needs.
.
The following are total daily caloric requirements for adult dogs of different weight ranges.  These are general values and are meant to serve as practical guides for relatively active, nonpregnant, nonlactating dog.  Remember that dogs that live outside in cold climates burn more calories per pound of body weight than those that sleep all day indoors.
                Dog’s Weight                    Caloric Needs
                     1-2 lb                     60 cal/lb of body weight
                     3-5 lb                     52 cal/lb of body weight
                     6-10 lb                   45 cal/lb of body weight
                     11-14 lb                 40 cal/lb of body weight
                     15-29 lb                 35 cal/lb of body weight
                     30-45 lb                 30 cal/lb of body weight
                     46-74 lb                 27 cal/lb of body weight
                     75 lb and up           23 cal/lb of body weight
.
Example: A 10 pound dog needs 45 cal/lb in one day.  Therefore, its total daily caloric requirements are 10 X 45 = 450 calories.  If you feed the dog twice a day, it should receive 225 calories at each meal.
Different foods vary in caloric content, but you can use the following general rule: Dry foods contain about 1500 calories per pound.  Semi-moist food contain about 500 calories per 6 ounces.  Canned foods contain about 500 calories per pound.  Special diets vary in their caloric content.

Feeding Orphan Kittens
General Information:
There are several possible reasons for hand-raising kittens: death or illness of the mother, inadequate milk supply, and rejection of the kittens.  Hand-raising kittens is not overly difficult and is very rewarding.
.
Kittens need a warm, draft-free environment during the early weeks of life.  Air temperature in the immediate vicinity of the kittens should be 85° to 90° F for the first week of life, 80° F the next 3-4 weeks and 70° to 75° F at 6 weeks.  The higher temperatures during the first few weeks may be maintained with heating pads, light bulbs, or heat lamps, but great care must be taken not to overheat or burn the babies when they are too young to move away from the heat source.  Clean paper or cloth is suitable for bedding.  A tall-sided cardboard box makes a safe nest and keeps the kittens inside until they are several weeks old.  Constant crying by the kittens indicates something is wrong.  Contact your veterinarian.  Also, the kitten’s weights should be monitored.  Consult your veterinarian if the kittens fail to gain weight.
.
Kittens may be fed by bottle or stomach tube.  The stomach tube is faster, but many people enjoy bottle feeding kittens.  Your veterinarian or clinic staff can instruct you in either method.  Newborn kittens should be fed 6-8 times daily.  The frequency should be gradually reduced to 3-4 times daily by 2-3 weeks of age.
.
How Much?
You can determine how much to feed an orphan kitten by considering its daily caloric requirements.  The general total daily caloric requirements for kittens under 4 weeks of age are:
  1st & 2nd week of age  6 calories/ounce of body weight daily
  3rd & 4th week of age  8 calories/ounce of body weight daily
.
In general, milk substitutes contain around 1 calorie per ml.
.
Example: A 1 week old kitten weighing 2 ounces requires 6 calories/ounce X 2 ounces = 12 calories daily.  If you are feeding the kitten 6 times daily, 12/6 = 2 calories per feeding.  Your milk substitute contains 1 calorie/ml, therefore you should give 2 mls at each feeding.
.
Solid foods should be introduced as a thin, pan fed gruel at about 3-4 weeks of age.  Over the next 2 weeks, the gruel should be gradually thickened to a normal solid consistency when the kittens are 6-8 weeks of age.
.
Kittens must be helped to urinate and defecate by gently stroking the genital area with a cottontail or tissue moistened with warm water after each feeding.
.


.
Feeding Orphan Puppies
General Information:
Puppies need a clean, warm, draft-free nesting area.  Air temperature in the immediate vicinity of the kittens should be 85° to 90° F for the first week of life, 80° F the next 3-4 weeks and 70° to 75° F at 6 weeks.  The higher temperatures during the first few weeks may be maintained with heating pads, light bulbs, or heat lamps, but great care must be taken not to overheat or burn the babies when they are too young to move away from the heat source.  Clean newspaper is a good bedding because it is easily disposed of.  As the pups begin to move around, newspaper should be replaced because it is slippery.  Cloth bedding offers good footing and is washable.  Constant crying indicates something is wrong.  Contact your veterinarian.  Also, the puppies’ weights should be monitored.  Consult your veterinarian if the puppies fail to gain weight.  In general, a pup should double its weight in 8-10 days.  Overfeeding can be worse than slight underfeeding.
.
Puppies may be fed by bottle or stomach tube.  The stomach tube is much faster and especially handy with large litters.  Many people, however, prefer to bottle feed because of prolonged puppy contact.  Your veterinarian or clinic staff can instruct you in either method.  Newborn puppies should be fed 3-4 times daily by tube feeding or 5-6 times daily by bottle feeding.  At 2 weeks of age, 3 tube feedings or 4 bottle feedings are usually sufficient.
.
How Much?
You can determine how much to feed an orphan pup by considering its daily caloric requirements.  The total daily caloric requirements for puppies under 4 weeks of age are:
  1st week of age    3.75 calories/ounce of body weight daily
  2nd week of age   4.5 calories/ounce of body weight daily
  3rd week of age    5 calories/ounce of body weight daily
  4th week of age    5.5 calories/ounce of body weight daily
.
In general, milk substitutes contain around 1 calorie per ml.
.
Example: A less than 1 week old puppy weighing 5 ounces requires 3.75 calories/ounce X 3.75 ounces = 18.75 calories daily.  If you are feeding the puppy 4 times daily, 18.75/4 = 4.68 calories per feeding.
.
Your milk substitute contains 1 calorie/ml, therefore you should give 4.68 mls (about 5 mls) at each feeding.
.
Solid foods should be introduced at 3 weeks of age.  Pan feed a thin gruel made by blending good quality puppy food with bitch’s milk formula.  Gradually thicken the gruel until no milk substitute is used at about 6 weeks of age.  At this time, the pups should be offered good quality puppy food 3 times daily.
.
Puppies must be helped to urinate and defecate by gently stroking the genital area with a cottontail or tissue moistened with warm water after each feeding.
.


.
Feeding Weanling Puppies
General Information:
Weaning is the process of gradually changing a puppy’s diet from mother’s milk to solid foods.  A puppy is considered a weanling from the time it receives its first food other than mother’s milk until the time it no longer nurses.  Usually this period is from 3-4 weeks of age until 6-8 weeks of age.  Early weanlings should be weighed frequently and their weight recorded.  Progressive weight gain and content puppies are good indicators of adequate nutrition.
.
Watch for these danger signs: puppies that lose or do not gain weight; inactive puppies that feel cooler than their litter mates; and puppies with poor muscle tone as compared to the rest of the litter.
.
Begin weaning the puppies around 3-4 weeks of age by pan feeding bitch’s milk substitute.  Because weaning the puppies are still nursing, they will regulate their own consumption from the pan, so you do not have to be concerned with the total amount they consume.  Milk substitutes can be purchased from your veterinarian, pet shops, feed stores, and pet departments at most discount or chain stores.
.
The first pan feedings usually consist of the puppies wading through the food and lapping very little.  Most puppies lap from a pan readily after 3-4 feedings.  When puppies are lapping the milk substitute readily (by 3 ½ - 5 weeks of age), blend the milk substitute and a good quality puppy food to form a thin gruel.  This should be offered to the puppies 3-4 times daily.  When the puppies are eating the thin gruel readily, the amount of milk substitute added should be gradually reduced and the gruel slowly thickened.  The goal is to eliminate the milk substitute by 6-7 weeks of age.  At this age, the pups should be eating good quality puppy food softened with water 3-4 times daily.  Water can be eliminated when the teeth have erupted and the pups are vigorously chewing.
.


.
Nutrition and Obesity
General Information:
Obesity is the condition of being seriously overweight.  Obese pets have more physical ailments and a shorter life span than those of normal weight.  Obesity increases risk during surgery, and breathing and walking are more difficult for the obese pet.
.
Obesity is usually the result of too much food and too little exercise.  Other factors, such as breed, temperament, hormone imbalance and disease, may also cause obesity, but most cases are the result of too many calories.
.
Weight loss should be accomplished slowly with a nutritionally, rather than with sever short term food restriction.  In most cases, pets must be retrained to eat moderate amounts of food 1-2 times daily without any snacks.  All members of the family should be aware of the need for the pet to lose weight, and all should be in agreement before starting dietary control.  One person can easily foul up the entire weight loss program.
.
Notify your veterinarian if any of the following occur:


.
Self-Feeding of Dogs
General Information:
Self-feeding is the practice of allowing dogs unlimited access to food.  It is a practical and efficient means of feeding the kenneled dog.  Most notable among the many advantages are: Caution must be taken with dogs that tend to overeat and become obese.  Self-feeding is not advisable for overweight dogs.  Some veterinary nutritionists do not recommend self-feeding programs for puppies less than 4 months of age.
