Thank you both!

It is really hard, there are nights that I'll have bad dreams about Charlie (hes an atopic dog and I had to give him Benadryl three times a day to try to prevent his allergies from popping up, but when he started scratching he'd scratch himself bald/bleeding and get hot spots and then he'd have to be on oral antibiotics and need a steroid injection just to make him comfortable) where he lost all his fur from scratching/etc... I KNOW my ex is not keeping up with the benadryl, he's only doing it once a day according to him (and I'm sure that's only when he remembers...). and I'll look at pics and just miss his goofy personality SO much... but I have to let it go. He isn't being neglected persay, he just isn't withholding the level of care I would have him at if I had him. He does keep his vaccines up to date and seek medical attention when he needs it. It's just hard, considering my ex has a baby now with the "lady" he left me for and I know the kid always comes first, so I do worry about Charlie...
