Sounds like you guys are working things out.
We have a Siberian Husky (6 yrs) and a Tennessee Mountain Cur (3 yrs) and my Flemish (8 months) gives zero f****.
She’s a big sturdy bunny so she’s chill anyway. Prior to her spay she had a major crush on the Husky. When she tried to get snugly he would softly howl at us, begging for help. She’s been living with them since she was 8 weeks old. We introduced her to the dogs leashed and and used baby gates and exercise pens as boundaries. The novelty was over when she started jumping her fence and totally ignoring them and they ignored her in return. It was great to see them all crashed out on the living room rug together for the first time. Now she thinks we are her warren/vassals.
All that aside, I manage their time together and I don’t leave her out at night or if I leave the house but other than that, she’s free range. We bunny proofed within an inch of our lives.The worst thing I’ve seen is that the boys will sometimes take her treats! that is infuriating. Like any self respecting dog likes cilantro or bananas. My experience is that large dogs are more relaxed than small ones. They don’t bark as much or have a bone to pick with everyone- something to prove. My dachshund was the one who chewed up the vet.
Zoe has plenty of hidey holes where she can lay low and avoid the dogs. If she’s over it she can go in her crate or behind the couch or under the desk. I keep an eye on everyone because it wouldn’t take much for them to hurt her- even without meaning to.
So I guess it depends on the animals. If both of your pets are young I would imagine they can all be trained to respect each other. Go slow and take some basic precautions but cohabitation’s working really well for us.
