So, I adopted my Dog Henry from Boulder Humane Society in November. He seemed healthy, we did not bother with taking him to a vet when we got him. Fast forward about 6 months to may, he was getting progressively more sluggish and drinking lots of water so I took him to the Vet who looked him over and said well he is just over weight cut his food. So, fast forward to this week. I noticed a sore on his tail, he yelped when I touched it. I cleaned it with warm soapy water and iodine. Took him in the the vet who ran blood work finally at my request. He came back with a UTI, and Diabetes. I am kinda pissed at Boulder Humane Society and the previous owners because I feel like they both ignored this dog. I will be taking care of Henry with 2x a day insulin for the rest of his life because He is a great dog and deserves to be healthy. Any other tips on dealing with a dog with Diabetes.
