Right, am a little shaken by this but I just gave my 10 week old puppy a raw bone with some meat on it and he ran into the garden and under the table. I then went out and tried to get him back inside as I wanted to keep an eye on him and he just kept running away from me. Then he ran inside into a little cat house thing - like a den. I was worried he might bite off too much bone or something so I went over and he growled really aggressively at me. But I still wanted to get the bone away so bent down and he growled v loudly again and sort of snapped. Clearly guarding his bone. I put loads of treats down and he ran out, snatched them but growled going back in. By this point I was pretty scared as he was behaving very oddly. So I put more treats down and hoped he would drop the bone but he didn't. I then picked him up and held treats close to his nose and he dropped the bone, I said good boy and picked it up, put him down and then left his playpen.
But I was actually quite scared. He has never displayed any signs of food aggression before - I could take rawhide away which is his favourite and always said good boy etc and can move bowl, put and take things out of bowl while he is eating. This bone seems to have been so amazing for him his wild guarding instinct came out, and it is a bit frightening as I was certain he would have bitten me very hard (for a puppy) given the chance...
What should I do!? Is this normal? I have temporarily gone off him! Def no more raw bones for the time being. Thank you in advance...
