I posted a few weeks back about our new 3 year old whippet (privately rehomed, we didn't get her through a rescue) who has separation anxiety.
We've had her for 6 weeks now and while the SA is very slowly improving she's now started showing resource guarding behaviour.
This is only towards other dogs and it's not so much about food or treats, but she angrily guards anything she sees as her space.....she's an angel on walks as long as we're on the move but as soon as we sit down anywhere she starts guarding that as her territory and hates other dogs coming near, barks at them and would probably try to chase them if she wasn't on the lead.
It's a tricky combination of problems as we can't just leave her at home if we're going somewhere she'll find triggering, as being home alone is terrifying for her too.
I feel constantly anxious wondering of things will ever get better and thinking wtf have we done. We're looking at behaviourists but I'm so scared this won't get better
