I have a 4 year old Cavapoo. He has always been a placid, but anxious dog because of his background and the environment he was bred into, however this has massively improved over time.
He has always had a little bit of resource guarding, but usually only a tiny bit of a growl and then happy to let you take the item if it was not appropriate for him to have.
He is currently going through a trial (chemical) castration. Potentially due to this, his resource guarding has got considerably worse where he will even growl at me now when he never used to, because of this if I have to take an item off him, I usually get him away from the item first by treats or a distraction and then remove it and this works fine.
Today, he was chewing on a piece of plastic and my partner attempted to take it from him, ignored his warning growls and did not do the distraction technique or try replacing it with something else, and it ended up with him biting her quite badly on the finger.
This is the first time I have ever been in this position and it has completely shaken the whole house.
Firstly, it is likely to need a hospital visit due to the punctures being quite deep. Does the hospital report this to the police? I also have a 10 year old child in the house (who knows not to go near him when he has anything in his mouth and respects his boundaries), will the hospital report this to SS?
Secondly, how do I handle this going forward? I already do the trading/distraction technique, I also suspect that the castration is making it worse so I will call the vets and ask for advice. But who was at fault? Was this a careless mistake on my partners behalf or is my dog no longer safe to be in the family home and is likely to be more aggressive after this first biting incident?
He is a very much loved dog and this was very very out of the blue despite his resource guarding issues, and we are all feeling incredibly heartbroken that this has happened so please be kind.
