AITA for not wanting to be responsible for my puppy?

So long story short I know how much work dogs are based on my parents getting a dog when I was in my teens. I love animals but am more of a cat person and thus got a cat because they are significantly less work than dogs. My cat is my responsibility I clean her litter box, clean up her messes, buy her food etc. My husband and son both wanted a dog specifically getting her as a puppy. I agreed under the pretense that she’s a family dog and I will help with meals, letting her out, etc but with all other puppy circumstances my husband takes care of the rest. My husband is an accountant so he is very busy right now however I took on a new position with his blessing and now am also super busy. I do all of the housekeeping and cooking even with working 60 hour weeks have now have found myself 100% responsible for the puppy. I love her to death but she is a puppy and super food motivated so despite our best intentions managed to get herself into some shitty situations. I am feeling incredibly frustrated because every time she has been sick (kennel cough, eating a grape, eating wasabi) I have been the sole person to stay up with her, taking her to the vet, until all hours and then go into work late because of these instances. I made it very clear before we got the puppy it was mostly his responsibility and the cat was mine (which I have 200% held up my end on). I did not want a puppy because of all of these reasons yet every vet/emergency appointment and night long vomiting episodes have fallen on me. He says I’m the AH because she’s our family dog and I should be willing to do these things but the whole reason I did not want a dog was for this. So AITA?
