Is it okay if I want to put my partner's dog down?
Why would you want to put your partner's dog down?
It has been so difficult to handle household items since the dog is around.
While it can be annoying to handle a dog, putting down a dog is a very serious thing to do. That would make a lot of people feel uncomfortable to know that you would kill an animal.
Ughhh... Why does my partner love that dog so much.
Sometimes people just really love their pets. Have you considered bonding with the pet and trying to learn to love it even a little bit? It may make the relationship a lot easier if that works out for you.
