Dog given to me by ex-boyfriend, now he wants dog back.
I have a bit of a complicated situation. My ex adopted a dog about 4 years ago. We started dating about a year and a half ago. About halfway through the relationship, we decided to part ways and he insisted that I keep the dog as he felt he would “hurt her” and he didn’t want her. I tried to support him and his mental health and insisted that she was his and he continued to try and push me to take the dog and I finally said yes. I brought her to the vet and found out she had gotten Lyme disease (he was not giving her tick or heart worm preventatives) so I treated that as well as her skin issues from allergies. This is all back about 6 months ago and now he is stating he wants the dog back and he was in a bad mental state. What can I do? Do I even have a case if he had the dog for 2 years before I even entered the picture?
