Can a male dog penetrate another dog?

well if you have a wild dog that did not go to the vet and a other wild dog then yes. but if the two dogs went to the vet then no. if one did go and the other did not then yes/no. yes because their might be something with the type of dog it bloodhound no because the girl dog that goes to the vet all the time and is healthy and never gets sick then no. if you want more info look it up at vets websites.
