i found my dog on the side of the road i know he is a pit bull but can i go online somewhere to find what breeds hes mixed with example(gatorandrednosedmix)by putting in his markings?

Try www.dogster.comIts an active forum for ALL kinds of dog issues, such as even trying to determine the breed/s. All you need is a picture.These are just guesses though.There is no genetic testing to find out for sure what breed/s your dog is.or, go to your vet and ask them if they have an idea...
