I used to have a rabbit (the 4 legged furry kind) I'm sure he thought he was a dog, he'd run after a tennis ball if I rolled it on the grass, didn't bring it back tho and would sit next to me whenever I sat on the back patio step, and came when I called his name.
I thought he was a female for about 18 mths, until the day he started trying to bonk my black furry slippers whenever I went in the garden
. I had to put my gardening shoes on to peg out the washing or he'd be hanging off my foot
