The animal shelter I work at got in a Boxer who gave birth to a litter of pups seven weeks ago. This week they are up for adoption. The mother became so aggressive she had to be moved to a special foster home since the shelter could not handle her. She had seven pups, 5 males and 2 females. We think they are a Lab X Boxer. My question is, what are the chances of the puppies becoming aggressive as they grow up? I know that some of the temperament of a dog comes from the parents. This shelter I work at , not the best in my opinion, doesn't really warn people about the things they even see the older dogs doing half the time.
