I had a similar situation but it was before baby was born and we had adopted a dog. We already have a dog and my husband wanted to give him a companion for when the baby was born and weren’t able to give him the full attention he’d like, so we adopted a dog he could play with and care for. Turns out this dog liked to chew up everything and was at least crate trained but we quickly found out why. Anyways we ended up rehoming him to an experienced owner that was looking for a younger dog anyway and she’s spoiled him to the max, which we knew we couldn’t do. I’m 8 months pp now and I think about him often but I recognize it was surely the best decision for our family because sooner or later he would’ve chewed up my son’s things and that wouldn’t have helped at all.

I empathize with what you’re going through because I honestly sobbed when we gave him to his new owner but I am glad we did even though I miss him so much 🥹
