It is high risk anaesthesia as the dog is very old at 15 years. The 2 family vets advised medication for the past months, but this does not resolve the problem of the tumour growing larger and soiling the pampers and flooring. The owner surfed the internet and consulted me.
"It is high anaesthetic risk," I told the owner. "The dog does not have heart or lung problems on physical examination but he is aged."
