What Determines Average Litter Size for Dogs?

What is the average dog litter size and if my female is having small litters how can I safely increase her litter size? The average size of a litter depends on the breed of dog. For example, the smaller breed dogs may only have one to three puppies while larger breeds can have eight and up to 14 puppies.

What Can I Feed My Dog to Increase Litter Size?

Superior nutrition, good body condition and excellent parasite control are important methods to improve the number of puppies a female dog has in her litters. Adding Breeder’s Edge® B Strong to her food ration and using a high-quality puppy food that is NOT grain free is recommended. Keep her at an ideal weight and physically active and fit. Making sure to use monthly flea, tick, heartworm and intestinal parasite control products will assure she is in peak health at the time we expect her body to be able to metabolically manage the all important canine pregnancy. Reproduction is a luxury of the body – only animals in excellent health have the resources to produce sperm, eggs and support a healthy canine pregnancy.

Whether your dog is having one or 14+ puppies, make sure you have your whelping supplies on hand so you are ready.
