Diaz' Heart Animal Hospital 4172 West 12th Avenue, Hialeah, FL 33012

"Vet Jose Diaz kept me waiting for 40 minutes, engaging in personal calls and informal conversations with the staff. When he finally examined my dog, he was in a rush, he asked the staff to run tests and then left to pick up his kids from school. Upon his return, he provided the wrong results for another dog, stating that mine had no issues. It was only later that one of his staff members informed me of the mistake, and the veterinarian didn't apologize in person. The lobby was crowded with other patients waiting as well. While the staff is friendly, the overall lack of professionalism makes it difficult to recommend this clinic."

"Dr. Diaz is a great vet! Ive been taking my 3 dogs there for many years! Always attentive, knowledgeble, and helpful! He treats and resolves my dog illnesses! The staff is amazing and I am very happy I found him!"

"I am going to speak from my experience over the years with three little dogs, 17 and 16 years old respectively, Rocky, Chloe and Frankie, I have been in this clinic for around 15 years and I can only say that the doctor and his team are very respectable for their clients as loving and humans with each animal that arrives for follow-up as well as for help, and seeing his concern for each different case, the doctor is available 24 hours for his pets, whether on holidays or weekends, he answers the phone and in my case I had that need on a Sunday. and in 10 minutes I was already at the clinic seeing my dog, I give them more than a 5, I would give them a 100%, thank you Doctor for all your help for those of us who love animals, it is invaluable."

"Diaz Heart Animal Hospital is the very best. The care is the very best. Dr. Diaz is unlike any other veterinarian I have ever had for my animals. His bedside manner is unremarkable. His staff is loving and caring. I always feel like family here. I totally recommend Diaz Heart Animal Hospital. He is knowledgeable, courteous and responsible."

"I am only leaving one star because it doesn’t give you the option to leave none or negative stars. I am highly disappointed with this animal hospital. The vet killed my two puppies that if it wasn’t for his misleading information and lack of knowledge they would still be alive. He robbed our family a chance to watch our puppies grow up. He treated their dad for parvovirus and we took him the puppies to get tested. Without consulting with us they tested negative so he gave them the vaccine and failed to inform us the virus has a 14 day incubation period. He stated we had two healthy puppies and we had nothing to worry about. Yet come 2 days later we were back with the puppies due to vomiting blood and showing symptoms. He barely treated them and 3 days later the puppies were gone. When I asked him why he gave the vaccine knowing it has an incubation period he said he gave them an antibiotic yet on the records it clearly stated he gave the vaccine. When we called other vets because we knew something wasn’t right they all told us they need to be negative for 14 days before we hice the vaccine or they will die especially being 4 months old and the father just had it. They were high risk. But his lack of knowledge and care for them lead them to their deaths. If anyone cared to read this I beg you! Don’t take your animals here! He is ruthless."
