ABSOLUTELY thank you for letting me draw her!!

I understand completely 🥺 my pup does the same while waiting for me
She sounds so sweet and was so lucky to have you while she was around 💜

Oh my gosh, soren, I'm so sorry for your loss
That's absolutely terrifying
I hope you are okay and don't be afraid of taking time for yourself while you mourn. Pets are family
