Hello everyone, my Ozzy was started on Vetsulin, 2 units twice a day on Tuesday. His numbers are going down since his high of 500 on Tuesday--this morning before eating he was at 247 and two hours after his shot he was at 227. However, he is a hot mess. He is sluggish, grouchy, and goes to sleep almost immediately after the shot for a good four hours. A little while ago he tried to jump up on the couch and missed it!! He then took a swipe at our dog, who is his pal, and got him across the face and all the poor dog was doing was walking by! I did call the vet and he wants us to lower the dosage to 1.5 starting tonight. Are behavioral changes normal? Do they get better? The vet originally wanted to start Ozzy on Lantus but the way that it was explained to us was that the prescription would be $304 every 25 days and we just can't afford that. Any advice is appreciated.
