The best thing about our animal friends, MDD is that they're more capable of unconditional love than we are!
Your furry friend will forgive you, buy or cook her some treats, take her for a nice walk (and let her smell everything she wants to), cuddle her and play with her (use an old stuffed animal and throw it around for her), reassure her with 'good girl'. She will forgive you.

I had this feeling the other morning actually, my family had eaten chicken one night and put the bones in the garbage. One of my dogs, as lovable as he is, always goes garbage picking. I woke up around 5am to find him coughing and vomiting, when he went outside he ate a bunch of grass to help him throw up some more. He ate the bones! Despite being the vegetarian, I immediately felt like a total ****. Why wasn't I more vigilant? Now he's going to have to go to the vet and have x-rays and surgery. Why is he looking at me like he's terrified and I'm the worst person in the world? I monitored him the next few days and he came out of that dilemna no problem, after awhile he was playing and smiling. He's back to his regular garbage picking self.

I know the feeling. They are creatures who rely on us for complete care and the unconditonal love they give, back.

She will forgive you. Work on accepting your mistake, we're all fallible, you're not a horrible person --especially considering you didn't do it intentionally, it was an accident. If we just vow to our animals to be more conscious the next time and show them the love that we can, things will work out.

I've never found people as forgiving as animals.
Much love.
