Mavricks Heart

Hi my name is Shannon and my 10 mo old goldendoodle got sick last week and we think it's his heart and he has to go see a cardiologist he spent all last week at the vet and he is currently at 1400.00, they let me take him home tonight but I have to take him back tomorrow for more tests. He is on over 6 medications as of now. We would appreciate any help with his vet bills. Mavrick is a sweet boy and so young to be going through all this and hearts are just breaking
