We have had a gruelling few days. Our rescue (2 year old male, mixed breed with some kind of sight hound) arrived home last week having previously been in foster care with a resident cat, which he never showed any aggression or prey drive towards.
We did scent swapping of blankets before he arrived, as well as a couple of day trips here over the last month, and they went very well with lots of treats and praise, a bit of bottom sniffing (dog to cat) and no signs of danger.
The first night home was similar - the cat is super chilled out and curious about the dog, and cautiously approached him without issue.
The last two nights have been a different story. One time, the cat approached the dog cautiously (no aggressive body language) and the dog absolutely went for him. Thank god I was sitting right next to him as he lunged at the poor cat, barking, growling, mouth open. I honestly have no doubt he would have killed him had he managed to get to him.
We were very shaken but hoped it was new dog insecurity after a bit of a stressful day (he is very reactive to visitors at the door and had a stressful time when a neighbour came over which took a lot out of him).
The following day was much better and in the evening he was chilled and settled. We were much stricter with access between the two but Cat - brave soul that he is - came back downstairs to hang out and hovered the other side of the pet-gate to the lounge. He wasn't fluffed up or dominant in any way. Dog was curled up in his bed on the other side of the room, but a few seconds after noticing the cat he leapt out at lightning speed to get to him.
We are now petrified the cat will come to harm. Our first priority is to keep him safe - this was his home first and we love him to pieces - and we thought we had struck gold with a dog that was proven to be cat friendly, paired with a very relaxed cat.
We can't help but think the dog is somehow triggered by our cat in a way that he wasn't by the other one and that even if we can get them to go weeks or months without incident, it would only take one bad day for him to randomly turn on him - especially out in the garden since outdoor mode is so much less controlled than indoor. The cat is 11, and much slower than the dog in a straight line, so he could definitely be caught.
We are emotional, exhausted, in all sorts of confusion and uncertainty. I have a constant knot of anxiety that the cat is going to be hurt and that we'll never truly be able to relax with both of them. Yes, we can have the dog on a lead all the time and make sure they don't have free access to the garden together, but what kind of life is it to always be on guard like that?
We came to the decision to return the dog after last night's episode but are now going through all the awful emotions of guilt and self-doubt, not helped by hardly any sleep for over a week coupled with shock at what could have happened.
Sorry this has been so long, and I am not sure what I am hoping for by posting. Maybe support that finding him a cat-free home is the right thing to do?
I know with lots of time and patience dogs can be trained to be less reactive to cats, but they are never truly 100% safe are they? Why would they be? It's in their genes to attack prey exactly the same way that our cat catches mice.
It makes me cry to think how stupid we were not to realise that before we took him in.
