Time and time again I have seen or heard of breeders who have dogs that are not getting pregnant and having lower sperm counts. Well, guess what we have a reason for this. Fat dogs and borderline obese dogs alike are not fit for breeding. Many people are claiming to be βbreedersβ who are doing nothing more than feeding their dogs in cages every day running a puppy mill. If you look closely, you can tell which dogs are not getting the exercise and overeating. One thing that is very important for us to consider is the fact that dogs and humans have evolved over millions of years along side each other. Many of the problems in dogs directly correlate with the issues that we have as humans.
We can directly see the relationship between obesity and infertility. Obese dogs and people have fertility issues. The fact of the matter is lazy fatter dogs are less fertile. So be good to your dog and help him be as healthy as possible.
