Micro bully, she is only 30 pounds and barely 10 inches tall. Smidgen is a 9 month old rescue pup. She had a rough life in her first few months, born in a backyard breeding situation, having her ears cut off and never seeing a veterinarian. On her first vet visit after we rescued her, they discovered she had a grade 4 heart murmur. Being such a young puppy we were very concerned so we made an appointment to see the cardiologist at the University of Florida in Gainesville. She spent the day there getting an echocardiogram and a bubble test. They found she has two heart conditions. Pulmonic stenosis and PFO. The veterinary surgeon said they could do a balloon valvuloplasty to reduce her murmur so we scheduled surgery. Smidgen had her $3500 surgery on March 17th but 25 minutes into the procedure as they were placing the catheter into her heart, she shunted. This caused her oxygen levels to plummet and they immediately stopped the procedure and decided it ws best to not proceed. On a good note, the vet said that since she's been on the Atenolol, her pressure grade level has dropped so she can live a normal life as long as she is not symptomatic. It has been quite the journey with much anxiety, anticipation, and heartache and although Smidgen was unable to have her heart fixed, she is alive and still full of life :). She has never shown any symptoms and nothing stops her! She is rambunctious and the sweetest dog you will meet. She is FANTASTIC with other dogs and cats and loves all people. She will need to take 25mg of Atenolol daily for the rest of her life and fortunately it is a relatively inexpensive medication. She has 6 bottles of 100 pills that will come with her at adoption.
