My (30F) husband (31M) refuses to do a chore. How would you solve this?

My husband and I have been together about 8 years, married 3, with an anxious dog. He goes to work in an office and I wfh so our dynamics for the housework lean a little more in my direction, but he takes advantage of it.

I always take care of the dog, all the time. Vet appointments, walking, activities, daycare, etc. All me. When we first got her, we both split her responsibilities. I never had a dog and he came from a family with a dog, so I thought he knew more than me. But then he quickly just started doing the bare minimum, and that eventually turned into “forgetting” to feed her.

I’ve addressed it more than once, and he will start picking up his slack for maybe a week, then go back to being “forgetful”. That makes me have to ask him outright do things for her, or just do it all myself. I usually end up doing things myself I just can’t trust him to do anything on his own.

That’s insanely not fair to me. We’ve talked about kids recently and are excited to start planning, but with this aspect I’m scared to bring more responsibilities into our life if he can’t even do something so simple.

It makes me feel really sad and trapped doing this particular responsibility. My main gripe is that he just never offers me a break. Just expectvs me to take care of things. He doesn’t even offer to take over when I’m sick or busy.

I’m just frustrated. He doesn’t make my life any easier when it comes to this. I know something has to change.
