Pike is sick

So as many of you know we adopted Pike and he is now part of our family. We had heard some horror stories about people getting sick dogs from LHS so we decided to take him to our own vet just to make sure he was in good health. Unfortunately we found out that Pike has a tumor on one of his toes, he has heartworm, hookworm, and a tick disease, double ear infection and tooth decay. We did get insurance on him but they are not going to cover the heartworm the hookworm and the tick disease. The vet bills have already racked up 400$ and is estimating it could cost around $2,000 which is fine except that don't bill you they need it all at once. Om top of that our bunny is ill and we are paying vet bills for him as well. Any donation towards the cause would be so kind we love him and we can't get rid of him we made a vow to be his parents and we will see this through so that he can live a long life.
