What do you plan to do with your dog? I guess then it would depend on which breeder you chose.
We have alot of good breeders in Canada. Go to the RCC website
www.rottclub.ca and take a look.
Also be cautious of imported dogs being bred in Ontario. I know that we have a few members that bought pups from German import parent's and the pups have been diagnosed with heart problems. Many European breeders do NOT do heart or eye certifications on the dogs they breed.
