hey I'm just writing today to hopefully see if anyone knows what could be wrong with my dog. My dog is a staffy x mastiff and he's had a perfectly normal upbringing just been your usual dog but it got to about being a year old when he developed a really bad behaviour. Sometimes not all the times he won't let you touch his toys, sometimes he'll happily let you take them but sometimes he could rip you hand of. Most recent event was yesterday I was petting him when he had his toy and he just started growling so I thought I'd discipline him by taking it off him but then all hell breaks lose he starts snarling backing off into a corner growling like a beast. But this is what concerned me he dropped the toy and walked in front of me doing the same thing. Like this thing no longer became about the toy. I did stand my ground and he did back off and only after talking to him in a soft voice to calm him down he returned to normal. I swear he's got ADHD or something the tiniest thing can set him off.
