Hi!
I hope you can get this sorted out okay..I know it's hard to afford but maybe it will work out. I have seen pets grieve for humans, and it seems the same as when they grieve for another pet. My cocker spaniel "Sparky" was hit by a car and killed a year ago, and my other dog, a pug named "Sumo" had a hell of a time adapting. He refused to eat, slept all the time, and was very lethargic. If you wanted to show him affection, you had to go get him and pick him up and "force it on him. We got another dog "Joey" who is a shepherd mix, and now all is well. I hope this helps...
