He sounds like an awesome dog!
He's 11+ years old now was assessed by vets as an approved medical alert dog for my epilepsy for 6 and a bit years. The term pitbull is very loose for any dog that looks like him and his mum but hes never attacked anything with any intent, all 3 of the dogs that went for me were labradors of sorts... but my dad has 2 labs that are lovely and all that makes a dog what it is, is its family and lifestyle.Handsome pup. Considering your location though, saying that your dog is half APBT (especially since he looks like it) isn't a good idea, unless they've repealed the Dangerous Dog Act and I just haven't heard about it.
