Hi Julie.
This question has alarmed and upset me. Not entirely sure what the deal is, but it seems your husband treats dogs as entirely disposable, which is an appalling attitude.
I am certainly not judging, but as you asked, your husband is acting like a selfish, thoughtless t**t.
I hope he never gets another dog. It is sad that you pick a family pet together and he thinks he can just "get rid".
wildwood I would suggest that you are being very presumptious.
Dogs truly are for life, and should only be given up in exceptional circumstances. To do this without even consulting you is at best thoughtless and at worst downright cruel. Why don't you take him to the local rescue and let him see where some dogs end up because of people with attitudes like his?
And while you're there, see if they'll take your husband and find you a new one.
Let us know the outcome of this, it's really disturbed me.
