My partners 12 yr old boxer dog has been shaking so taking her to the vets blood tests said there was high potassium and also a lump in her stomach but due to her age thinks best to leave it, she doesnt seem in any pain she does need to go to the toilet every couple of hours or theres an accident and still sleeps in a hard bed, what is best to keep her comfortable and why is she shaking?
I wouldnt be happy to leave her shaking as she could be in pain, and as Kita says, would try another vet for a firm diagnosis and treatment to keep her comfortable.
