My dog is taking enalapril for his heart, a bronchodilator theo-dur, previcox for his arthritis & optimmune to produce tears for his eyes. His health has been declinging in the past year. In the past 6 mos, he only gets up to go outside & to eat. Which I contribute to loss of stability in his hind legs. I recently made a ramp to assist him in going outside which still required assistance by a family member. He's been vomiting off & on lately. Other than going outside to the bathroom & eating, he no longer mobile. This morning I went to assist him to go outside & noticed he had vomited & urinated on his area of the rug. He couldn't stand w/ assistance & his head tilted to the left in a stiff manner & his eye was blood shot moving up & down. What's going on? Also he's a 15 yr old cocker.
