Diagnosing diabetes in dogs is easy to confirm with simple tests for glucose (sugar) in the blood and urine. Dogs, just like humans, experience pain and we aim to alleviate the pain associated with needles. If you want to provide your dog with leading care, think about purchasing this device.

How it works?

Liquid medications are transferred into the needle-free nozzle/syringe via adapters. For insulin, we have a vial adaper and an insulin pen adapter. The needle-free nozzle/syringe can contain up to 0.5ml per single injection. After loading the injector, the liquid medication in the nozzle/syringe is propelled effortlessly as a small jet into the body via a spring-action.

The liquid medication disperses into the subcutaneous tissue via the path of least resistance, in a cone-like shape. No sharp needles are penetrating through delicate skin and tissue. This reduces the likelihood of tissue damage, the formation of scar tissue and the chance of developing lipo-hypertrophy (lumps under the skin caused by multiple injections in the same area of skin over an extended period or reusing the same needle without correct sterilization). Insulin is delivered the same way as for humans with our certified subcutaneous injector.

The Comfort-in needle-free injection of insulin for dogs is fast, safe, quickly absorbed by the dog and ‘virtually’ painless. Needle-phobia and the discomfort of ongoing needle injections is a real barrier for many people or animals who require ongoing medical care.

Converting U40 Insulin Units for U100 Insulin Syringes

What is the difference between a U40 insulin syringe and a U100? Well, the main difference is that the marking measurements are for different concentration of insulin. U40 insulin has 40 units of insulin in every ml, and the U100 has 100 units. Therefore, when converting from a U40 syringe to a U100 syringe you are required to multiply your U40 units by 2.5.

40 x 2.5 = 100

Never dose U100 insulin with a U40 syringe as you may put your animals life in danger. Consult your vet if you need more information.

Below is a conversion chart of insulin for dogs with calculations already done.

    The Comfort Inn system has saved my dog, literally. I was unable deal with handling syringes and needles, and this system has made it possible to get his diabetes under control. I cannot say enough about it.

    I have a diabetes dog who despite using every possible means of incentive would not initially accept the traditional needle injection of insulin. The folded skin with needle insertion was absolutely prohibitive. Other means starting with a needle also went nowhere. This needle-free system was the only acceptable alternative. It takes a bit to be patient with the instructions and to be careful with the unit conversions; but if you take a day or two, you'll be all set. It is important to get your pet used to the snap and pinch that goes with the injection, but that can be taken care of with a few additional treats.

    Amazing product. My dog is diabetic and he absolutely hated needles. This has made giving him his insulin so much less stressful. Customer service is excellent as well! 10/10 product.

    I have been using the Comfort In Needleless System for about a year, now. When I tell you it was a lifesaver for us, it is no exaggeration! Our little chihuahua was diagnosed with diabetes and needed injections twice daily. She was a maniac anytime I tried to inject her with a conventional needle and syringe. Several times she bent the needle and she would bite me-tried 2 kinds of collars but she always found a way! Rarely got the full dose and I was a basket case worrying! I looked online and found the Comfort In where you don’t need to use a needle at all! Other things I found still used needles. I ordered it and it was like a miracle for us! No more bites or partial doses!!! Also customer service is the best! I highly recommend giving it a try if you or your diabetic dog or cat hates needles. You won’t regret it, believe me! They even have videos to show how to use it.

    We have a miniature schnauzer that was diagnosed with diabetes and she is very difficult to give a regular syringe shot too. The Comfort-In needle free injection has been a life changer for us. We went from it sometimes taking 3 people to give her a shot to just one person. I appreciate the great customer service, so very helpful!! They go above and beyond to walk you through every step and make it simple to use. Thank you for making our life easier. Highly recommend.

    I can’t say enough good things about the Comfort-in injector - I don’t know what I would do without it! I use it for my diabetic dog who is highly adverse to needles. It was a struggle twice a day, every day, to give him his insulin injection and it got to the point where my dog resisted the needle so much that I couldn’t give him his shot without another person to restrain him. The Comfort-in has been life changing. Now shot time is no big deal and there’s no stress for me or my dog. And the staff at Comfort-in have been hugely helpful (and very responsive) in answering any questions I’ve had along the way.
