Can increasing Humulin dosage cause blindness in dogs? Should I be worried?

After adjusting the Humulin dosage for my dog, I've noticed he's been bumping into things more than usual, especially around the house yesterday. It makes me worried that the insulin change might be affecting his vision. Could the increased dosage lead to blindness, or should I be concerned about something else?

Answer

Your dog's recent difficulty in navigating around the house could be due to vision issues, potentially linked to changes in his insulin dosage. While vision changes can occur in diabetic dogs, it's important to identify the cause to ensure your pet's safety and comfort.

  • Monitor changes in behavior and mobility closely.
  • Vision changes can sometimes result from fluctuations in blood sugar levels.
  • Consult a vet to assess whether the current insulin dose is appropriate.

It's important to understand that while insulin adjustments are necessary for managing diabetes, they can sometimes cause temporary changes in blood sugar levels, affecting vision. Your dog’s sudden clumsiness may be due to fluctuations in these levels. Diabetic dogs can sometimes develop cataracts, leading to impaired vision. In any case, a vet should evaluate the situation to determine whether the insulin dosage needs further adjustment or if there are any other health issues contributing to these symptoms.
