My 7 yr old labrador- Oreo, was diagnosed with diabetes a few months ago, and we used to take it to the vet for shots. But as to some difficulty I came through in my life when the pandemic struck, I no longer could take him to the vet now like before. I had to find an alternative for my poor thing, he is the only one left for me in my life. I researched it and finally came upon a solution that insulin shots can be given in as in-home insulin kits available in the market. My concern is whether it would be harmful to him. Could anybody help me?
