Hi there, we have a 13.5 yr old bullterrier, not sure whats go,, shes flat, having trouble walking, shes vomiting about 3 times a week. Shes drinking, peeing and poohing normally...She was diagnosed with liver cancer 15 months ago, its not that, she had an ultrasound done yesterday no change, she just looks so sad? This started about 8 weeks ago, she was down the beach, she seemed a bit odd, she threw up on the way home, but that could have been the weather, we are in Australia, the vet checked her heart, that's all good, she had a blood test done too, waiting for the results.
