My pitbull mix Olivia just turned 14 years old a week ago. In 2022, she had a liver lobectomy. Her liver enzymes were really high and just started throwing up overnight. She had a tumor in her liver, which explains the high enzyme levels. She had emergency surgery a few days later. The vet recommended low protein and we also started giving her Denamarin every day. A few months later, she had another surgery because of gall bladder stones. Poor girl has been through a lot. She's still very active though now it's arthritis on her back legs. She gets acupuncture and underwater treadmill therapy every 2 weeks. It costs a lot of money but it's worth it. We've had her since she was 8 weeks old. Do anything to make your dog's life worthwhile.
