Simplify Diabetes Management and Insulin Dosage with HardyPaw

Keeping a diabetic pet healthy takes daily dedication and the right products behind you. HardyPaw stocks vet-recommended insulin options for dogs and cats, including Vetsulin, ProZinc, and Lantus, along with everything else you need, from insulin syringes and glucose monitoring tools to diabetic care accessories.

For pets newly diagnosed or currently under treatment, our selection supports long-term blood sugar control and improved quality of life.

Always ensure your pet has eaten before administering insulin. Giving insulin to a pet that has not eaten can cause dangerously low blood sugar. Contact your veterinarian immediately if your pet refuses to eat at injection time.

Trusted Insulin Products for Pets

Prescription Insulin for Dogs and Cats

All insulin products require a valid veterinary prescription. Never adjust insulin dosage without consulting your veterinarian.

  • Vetsulin for Dogs and Cats: An intermediate-acting U-40 insulin used to manage diabetes in both dogs and cats. Requires a veterinary prescription and regular glucose monitoring.
  • ProZinc Insulin for Cats: A long-acting insulin prescribed for feline diabetes. Requires U-100 syringes and veterinary dosing guidance.
  • Lantus Insulin for Cats: A commonly prescribed option for feline diabetes management, available in both vial and SoloStar prefilled pen formats. Both contain the same insulin -- the SoloStar pen offers a more convenient option for at-home administration. Requires U-100 syringes.

Important: Always use the syringe type that matches your insulin concentration. Vetsulin requires U-40 syringes, while Lantus and ProZinc require U-100 syringes. Using the wrong syringe can result in serious dosing errors. Confirm the correct syringe type with your veterinarian.

Insulin Syringes and Supplies

  • U-40 insulin syringes for use with Vetsulin, available in multiple sizes for accurate dosing
  • Insulin injection tools and safety accessories to support safe and comfortable at-home administration
  • Sharps disposal containers for safe needle disposal

Managing Diabetes in Pets: What You Need to Know

Diabetes in pets, especially in senior animals, is more common than many realize. Without daily insulin injections, high blood sugar can lead to complications, including weight loss, lethargy, urinary tract infections, and, in dogs, diabetic cataracts.

In dogs, poorly controlled diabetes can eventually lead to diabetic cataracts. Regular veterinary monitoring helps prevent this and other long-term complications.

Dogs and cats with diabetes may show a number of telltale signs, such as:

  • Excessive thirst and urination
  • Weight loss despite increased appetite
  • Lethargy or weakness
  • Poor coat condition

Getting the diagnosis right and finding the correct insulin type and dosage for your pet requires proper veterinary input. HardyPaw lets you order pet insulin and get your diabetes supplies delivered straight to your door with ease.

FAQs about Diabetes and Insulin Medications

Q1: What is the best insulin for cats with diabetes?

Ans: Lantus (glargine) and ProZinc are two of the most commonly prescribed insulins for feline diabetes, each with different pharmacokinetic profiles. Your veterinarian will determine which is most appropriate for your cat based on their individual response and health history, and will advise on correct dosing and syringe selection.

Q2: Can I buy insulin syringes for pets online?

Ans: Yes. HardyPaw offers insulin syringes specifically designed for use with pet insulin. Always confirm with your veterinarian which syringe type matches your pet's insulin, as using the wrong concentration syringe can cause serious dosing errors.

Q3: How often should I give insulin to my diabetic dog or cat?

Ans: Insulin frequency varies depending on the type of insulin prescribed and your pet's individual response. Many pets are managed on twice-daily injections roughly 12 hours apart, but your veterinarian will determine the most appropriate schedule and dosage for your pet.

Q4: What other supplies do I need to manage pet diabetes?

Ans: Besides insulin and the correct syringes, you may need a glucose monitor for pets, a sharps disposal container, prescription food or treats formulated for diabetic pets, and regular veterinary consultations for bloodwork and dose adjustments.
