I am not up to date on current rabies vaccines for dogs, but I know that in the past there was more than one formulation, as my next door neighbour's dog had an anaphylactic reaction when vaccinated and the vet made a note to use a different formulation for the next annual shot. In future the dog had no difficulties. There are known side effects to most vaccines. Aggression is not one I am familiar with, however, with rabies vaccination in countries that require it there isn't much choice. It would not be my first thought with an 18 month old dog showing aggression. Especially a Basenji objecting to being moved from a comfortable place.
Play mouthing & ending play time
Our 9 week old basenji loves to chew. For the most part, we've got this under control (by watching him carefully and replacing stuff he can't chew with stuff he can). Where we don't have this under control is when is comes to chewing us: every time he gets excited (ie play time) he starts nipping at us. He's not being aggressive, but it's still behaviour we'd like to "nip" in the bud. Lots of people seem to have had success with ignoring their dog for a little bit whenever he nips, so we'd like to try that, but we're unclear on a couple of points. First, how long do we ignore him for? And second, often he'll miss when he nips, sort of like snapping but much slower. Should we ignore him for this or wait until he actually connects?
How is your pup doing?
On all but the mouthiness front, he's amazing - he's friendly with people and other dogs, he loves to sit in our laps (for now at least), and he's doing well in the basic commands we are teaching him. We're so happy to have him around! But ignoring him has given mixed results and little progress in the last week. Remi just turned ten weeks so we are not too worried yet. At the same time, it sure would be nice if we could solve it sooner rather than later. Also, any suggestions on your dog's favourite chew toys are welcome. We've got Remi some nylabones to gnaw on for the moment.
