I became an irresponsible Pet parent 💔

I got my dog a year ago. I loved him he's very smart! This makes me have 3 dogs total. My dogs are my absolute world. I give them EVERYTHING. For years . I didn't think I could have children. They were my children but I got pregnant after trying for years and everything changed. My hubby is never here , he works 6 days a week 12 hour shifts. I'm alone with baby all the time. I breastfeed & pump I don't have time for the dogs. My 2 older ones are calm but the new one is too much for me. I ended up being one of those ppl who got a dog who can't handle (he's a malinois) I became everything I hate. I don't want him anymore. I can't take care of him. I don't have the money to train him anymore since im no longer working.. my plans for him changed. What do I do? I hope you guys can make me helpful info.
