Resource guarding me with new foster brother
I have an 8 YO Cav mix that was for a long time the singe dog in the HH. I just recently decided to foster a very non-aggressive mix that’s a little bigger than my cav-2 YO beagle mix for context.
My Cav has taken to resource-guarding me not just in food situations but in attention situations. Like, low thin warning growls and stepping in between me and the other dog when I’m cuddling the other dog.
In a food/treat situation he actually barked/snapped at the foster dog-so I’m obviously just removing/managing the food/treat situations but I’m at a loss of what to do with the other situations.
He used to do with my 1 YO cats which I was never really worried about because they would just take off and that would be the end of it.
The foster is very calm and so far has not reacted to any of this.
What can I do to curb this behavior in my Cav, and avoid actual fights and aggression etc?
