My dog was diagnosed with megaesophogus when my daughter was born. Basically, he regurgitates his food because the disease causes them to lose motility of their esophagus and so the food doesn’t go down it comes back up. So I literally have to hold him up for 15 mins after I feed him to make sure food goes down. While holding him, baby crying for me to hold her. Insanity. So yah, new mom, baby vomit and dog vomit all day long. Up until this day 18 months later ☠️
It sounds like you're just focusing your resentment on your poor pups. I know it's harder with them, but maybe you just need more support and a break. Do you have any family or friends around to help you? Can you try to do daycare once a week or something?
Give your dogs away, sell or rehome them. Taking care of your baby is more than enough. No need to add on extra stress to your plate.
I gave my dog to my sister-in-law cuz it was barking all the time and waking up my baby. So don’t feel bad or thinking you are a bad person, just give them to someone you trust temporary or even permanently if you don’t feel like you can handle them anymore
