Get Your Dog Care Questions Answered by Experts
Truthfully, we can only go by odds...the odds of your puppy having the ability and knowledge to breed at 4 months is slim to none...it increases each month...Now...there will be someone that may swear they have seen a 4 month old breed...but he is the age of about an 8yr old boy.
There is no absolute. We usually recommend neutering at about 6 months of age...since after that they do get the hormones going. I would recommend that if she has a female in heat to keep your puppy or her female separated.
Hope this helps.
