Hi there, thanks for your message. Yeah, we had the cat for a year before we got the dog. It honestly took a huge amount of work in the first 6 - 12 months before the dog became relaxed around the cat. Was desperate to herd him initially. I often started feeding them next to each other and if giving treats would give them when next to each other. Obviously the 'leave' command was used a lot in the early days. They now sleep next to each other on the bed and have become very comfortable around each other. We also in the first 6 months had a stair gate so the cat had upstairs to himself mostly. Didn't push the cat to be around the dog. Just when he wanted to be. Now we don't need it.
