John Heidi Badot from Halifax

On 1/24/11 I brought our beautiful 6 month old chocolate lab into Roberts Hosp lifeless and a heart rate ever increasing up to 300+ beats per minute. The staff that night was so caring and diagnosed him for treatment. Bubba was diagnosed with SVT. His treatment was medication that was ever changing do to his growth and the disease, therefore we were at the vet more often than we anticipated. His prognosis was grave and sadden the family each time he would have an episode. Each time we arrived at Roberts, which was at least once a week it was worse. The knowledge,love and kindness of Dr. Moses and his staff was amazing.Dr. Moses researched & found a fellow DVM Cardiologist K.Wright in Ohio that performed Cardiac Ablations on dogs (this is not done in Mass.anywhere which was unbelievable to us)We traveled to Ohio on April 21 to MedVet, Dr. Wright. Bubba was the 52nd dog, having a Cardiac Ablation, Perfect!!!If it wasn't for Dr. Moses his knowledge and his amazing staff we would have never got to that point. It has been 9 months, Bubba is a 85 pound healthy chocolate lab, truly 100%. I will always be grateful to Roberts Animal Hospital and their staff for one of the best dogs we've ever had. I would highly recommend Roberts Animal Hospital to anyone. Thank you all again & again, John Heidi Jonathan & Jeremy
