I took my pet dog to this vet and im so sad that all they care about is money. Pets are like family and when I took my dog for to get checked for vomiting They released her with a medication that isn't helping. I called back.2 days later to ask for help. I paid the vets 500.00 to help my dog and when I called them to ask if I could please pay for a different medication. I was told "take your pet to a different vet".. I feel really sad that I paid my last money to help my dog and she couldn't get the help she needed. There isn't any compassion here and will definitely never take my pets here ever again! I want to have my pet to get the medical attention needed and it be effective. Otherwise why did I pay 500 dollars for?
