Oh, I'm sorry you are facing such a tough decision
. I can't say what you should do, but it sounds like you are doing the right thing for your little guy. He will certainly miss you, but the stress will not be near as much as if he were taken from the only home he's known and his little dog friend, while also being left alone for so long every day. You should really feel fortunate that you can leave him with your mom and know he will be well cared for.
