Raising an orphaned puppy is a noble and rewarding experience. The bonding that will occur in the first few days will likely last for many years. However, orphaned puppies are very fragile; raising them requires jumping numerous hurdles. Do not be disappointed if you are not successful.
What problems am I likely to encounter?
Several critical problems must be addressed in caring for orphaned puppies. Among these are chilling, dehydration, and hypoglycemia. These problems are interrelated and may often exist at the same time. Close observation and prompt attention if any of these problems develop are essential to survival. Of course, proper feeding of the orphaned puppy is extremely important.
Chilling
Chilling in newborn puppies can lead to significant mortality. A puppy will dissipate far more body heat per pound of body weight than an adult dog. The normal newborn puppy depends upon radiant heat from its mother to help maintain its body temperature. In the absence of the mother, various methods of providing heat, such as incubators, heat lamps, or hot water bottles can be used.
Rectal temperatures in a normal newborn puppy range from 95º to 99ºF (35º to 37.2ºC)for the first week, 97º to 100ºF (36.1º to 37.8ºC) for the second and third weeks, and reach the normal temperature of an adult (100º to 102ºF) (37.8º to 38.9ºC) by the fourth week.
When the rectal temperature drops below 94ºF (34.3ºC), the accompanying metabolic alterations are life-threatening. Therefore, immediate action is necessary to provide the warmth the puppy needs to survive. A healthy newborn can usually survive chilling if warmed slowly.
During the first four days of its life, the orphaned puppy should be maintained in an environmental temperature of 85º to 90ºF (29.4º to 32.2ºC). The temperature may gradually be decreased to 80ºF (26.7ºC) by the seventh to tenth day and to 72ºF (22.2ºC) by the end of the fourth week. If the litter is large, the temperature need not be as high. As puppies huddle together, their body heat provides additional warmth.
Caution: Too rapid warming of a chilled puppy may result in its death.
Dehydration
The lack of regular liquid intake or the exposure of the puppy to a low humidity environment can easily result in dehydration. The inefficiency of the digestion and metabolism of a chilled puppy may also lead to dehydration and other changes such as those discussed in this paper.
Experienced breeders can detect dehydration by the sense of touch. Two signs of dehydration are the loss of elasticity in the skin and dry and sticky mucous membranes (gums) in the mouth.
An environmental relative humidity of 55 to 65 percent is adequate to prevent drying of the skin in a normal newborn puppy. However, a relative humidity of 85 to 90 percent is more effective in maintaining puppies if they are small and weak.
Caution: The environmental temperature should not exceed 90ºF (32.2ºC) when high humidity is provided. A temperature of 95ºF (35.0ºC) coupled with relative humidity of 95 percent can lead to respiratory distress.
Hypoglycemia
Signs of hypoglycemia (abnormal decrease of sugar in the blood) are severe depression, muscle twitching and sometimes convulsions. If a puppy shows signs of hypoglycemia, a solution containing glucose will have to be administered. A few drops of corn syrup on the tongue can be life-saving.
What do I feed my orphaned puppy?
Total nutrition for the newborn orphans must be supplied by a milk replacer until the puppies are about three weeks of age. At this age, the puppies are ready to start nibbling moistened solid food.
Preferred diets:
1. A commercial puppy milk replacer
2. For short-term emergencies:
l cup of milk
l tablespoon corn oil
l pinch of salt
3 egg yolks (no whites)
Blend mixture uniformly
Is the temperature of the food important?
Since the newborn may have trouble generating enough heat to maintain its body temperature, the milk replacer should be warmed to 95o to 100o F (35.0 to 37.8( ) for the best results. Testing the milk replacer's temperature on one's forearm (as for babies) is generally accurate enough. The milk replacer should be about the same temperature as one's skin or slightly warmer. As the puppies grow older, the milk replacer can be fed at room temperature.
How do I feed my puppy?
Spoon feeding is slow and requires great patience. Each spoonful must be slowly "poured" into the puppy's mouth to prevent liquids from entering the lungs. The puppy's head must not be elevated, or the lungs may fill with fluids. Newborn puppies usually do not have a well-developed gag reflex to signal this.
