Hi, I love with my 8 year olds and 2 cats. 10 days ago we rehomed a 5 month older rescue boxer from the RSPCA. They said he was cat tested and good with cats and children. He is great with children but just wants to chase the cats when he sees them. He has terrible separation anxiety. I have made the upstairs for the cats so they have a safe space (although one of them is still not coming in) and the dog is not allowed upstairs. I have to close the door to stop him coming up so he will repeatedly throw himself at the door and claw all the frames. I worry that he will hurt himself. I spoke to the RSPCA and they suggested a crate which could make I’m feel safe. This has had mixed results. Last night I came upstairs to bed and I could hear him panting and trying to get out. I went back down and he had managed to get half out of the crate by banging it (he’s very thin) I put him back in the crate, slept on the sofa and he slept absolutely fine. I don’t know what to do. The rspca told me not to sleep with him and start as I mean to go on but should I be? I have to leave him sometimes and what do I do then? I don’t have weeks and weeks to get him used to it before I can leave the house. I mainly work from home but about once a week have to go to the office for 2 hours and once a week for 6 hours. On the day I go for 6 hours he is booked in for doggy day care when my annual leave finishes. And I’ll need to go to the shops sometimes. Or do the school run without him. And I feel sick and sad about the cats, I feel like I’ve ruined their life. I’ve bought some Adaptil diffuser but don’t know if it will do anything, it’s not arrived yet. I’m sorry this is incoherent. I have hardly slept since I got him. I want to make this work, I don’t know how. If anyone replies, I will try to answer but I am at work today (from home) and might not be able to. I have also name changed as I didn’t want post linking to other posts but not sure if I’ve done it right so if it reverts to my usual name that’s why. Thank you for reading.
