YTA Yeah, you clearly described your moms major role in fucking up the Dogs Health. That’s sad, and disappointing. But to simp,y let the dog die because your mom fed him junk food is cruel and a clear abdication of the responsibility that you took on from the start. If anything, you could have intervened much sooner, since clearly you knew what your mom was doing was in fact going to destroy the poor Dogs health. Tbh, your mom sucks, too, and behaved selfishly, fooliahly, and cruelly in neglecting the Dogs Health. But you, supposedly you love this dog and you knew better all along. Sorry to be harsh, but WOW, neglecting a pet is horrible, and, given that you said you have the money, and you love the dog, amD you asked for a bunch of opinions, hell yes, cheaping out and letting the dog suffer an die prematurely to teach your immature mom a lesson. Yikes
