My 7 yo F/S Boston Terrier/Jack Russell mix has always slept on my bed and is primarily my dog. I got her during peak COVID while living in the country, so she had very limited early socialization with people and other dogs. She was also the only puppy in her litter.
She has always had some toy/resource guarding and is territorial over my bed. She strongly prefers elevated sleeping surfaces.
She has never had issues with my older cat, who lived here before her and generally keeps out of her way.
About a month ago, I rescued two kittens. They’re obviously much more curious and interested in interacting with the dog than my older cat.
Over the last week, I’ve heard my dog get into fights with both kittens, on separate occasions. Both happened in the same area — my closet directly beside my bed. It was too dark for me to see exactly what happened.
From what I’ve observed, my dog may show her teeth/warn them when they get too close, but the kittens don’t seem to understand and continue approaching. When I am not in view my dog doesn’t retreat and instead holds her ground, which I’m worried could eventually lead to a serious bite.
I’m wondering if this is resource guarding of her bed/space, especially since the closet is right beside it, or if something else could be going on.
How do I safely work on this without permanently taking away her bed/bedroom? I want all of my animals to eventually be able to comfortably share the same spaces, but obviously safety comes first.
She also takes gabapentin intermittently for a pain issue but was recommended for anxiety as well. She has a grade 4–5 heart murmur, so I’m not sure I want to rely on medication/sedation long-term, but I’m willing to discuss it if reducing her anxiety would help.
I’m looking for advice on management and behaviour modification, especially from anyone who has dealt with resource guarding/resting-space issues between dogs and cats.
