Shock collars are both unethical and illegal here. Training him to stay out doesn't work, because he sneaks in. Genuinely sneaks, caught him doing it more than once, he looks to see that I'm in another room and then goes to check the door so he can go in when I'm not there. Might be an age thing, but he's never been particularly obedient and is extremely excitable.
Were it not for the other animals I'd just use a lot of citrus scented oil to make my room absolutely stink of lemon or orange or something to keep him out, but as is that would be wildly unfair to the other pets, and maybe even unhealthy for a few of them.
As for unwanted, yeah, pretty much. 4* out of 5 people in the house at the time he was purchased voted not to get him. myself included. If it were up to me we'd just give him away, we're not a good family for a dog and he causes my father and I a lot of stress, as well as stressing the hell out of the cat.
*Two of whom have since moved out. Lucky buggers, but they do miss the cat dearly and aren't allowed pets at their flat so maybe not all that lucky.
I'm at the point of looking for a cheap single bedroom flat, but none of the ones in the area allow pets and Loki and Athena are non-negotiable on my end. Granted they might get a pass being reptiles and all, property damage and odours aren't really a big deal with them.
