I have three cats, one of them is super adverse to dogs, the other two do fine. I tried to get the cat to warm up, or at least tolerate a dog when I was dating someone but she always hid, and would crawl under blankets and tremble the entire time.
I tried to get her to get to the point where she could at least use the liter box, and eat and drink. I gave her a safe zone by putting up a gate she could get though but not the dog.
Since then I've stayed away from dating girls who have a dog. I like dogs, I've just had my cat for 9 years and don't want her to be unhappy. My sister's think I'm ridiculous.
You're making sure not to date people that are incompatible with your current lifestyle.
That seems pretty reasonable tbh.
