Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Cassie. A few possibilities exist. One is her dose (units) is too low or she is not responding adequately to the insulin (may need another type of insulin or may be having some insulin resistance). I would advise taking her to your veterinarian so that they can evaluate her and take a thorough history including how you handle the insulin, what she eats, etc. They will probably want to perform a glucose curve to see if the dose is too low or other things are playing a role such as insulin resistance or a change of insulin is in order. The curve can determine all of that. Again, this disease is challenging but I feel that your vet can make sense of all of this once a thorough history and glucose curve is performed. Good luck with Cassie.
