Hi all have a few questions for the board. I have a questionable on age and breed ?? Pitt..maybe?? My daughter bought a female from these people a yr. ago ..backyard breeder...she felt bad for the pup and fell in love with it every day as she jogged past her in her kennel. So she approached the people and they sold her Bella. She is short, stocky and pure muscle. Also more energy then a 1000 volts of electricity,smile. Well three weeks ago she called me and said ..Oh Mom, they have the sweetest baby for sale and I feel so bad for him..sighhh. I just happened to be visiting her shortly after and low and behold here they come to visit. Needless to say he now resides with me. Tried to get a pic of parents sent to my phone hasn't happened yet. Supposedly they own mom. They said he was 8 wks. However he has great balance & movement, as in not wobbly runs and jumps with ease. His eye's aren't blue anymore so I thought maybe 12-14 wks. The vet said 11 wks as he hadn't lost any teeth yet. That was 3 wks ago . I noticed he has lost 2 of his front upper teeth within the the last week. So at what age do they start to lose teeth?? I'm not new to the breed . My boyfriend came home with a pup 10 yrs ago..we had him till he was 5. Never had a problem with him when it came to animal aggression. In fact we had to unaltered male Rotts and Kane our Pitt also not fixed. It was the Rotts we had issues with and had to keep separate. Kane the pitt would go to lengths not to fight. I have several friends with them and they have no issues nor does my daughter. So I had no worries about this little guy...That is till I started doing research this past week reading forums. I am now worried and totally confused as to the difference between AMPBT, AMSTAFF, BULLY, and the dog aggression the forums are stating will be likely after a yr. old. I have a male and female Mastiff I show in conformation. So not fixed. Is it really a tried and true they will be dog aggressive after maturity? I like I said, never witnessed this with ours.
