    Love the U-40 syringes. I haven’t been able to find shorter length anywhere until someone pointed me in your direction. Has made life a lot easier and for that I am forever grateful.

    So glad to find these syringes. Much smaller and easier to give my diabetic dog his shots.

    Being new to this journey and not knowing all the correct terminology....I am grateful for the customer service. I had questions about the U40 shorter needle lengths and PetTest answered every question I have. I received the syringes and it has been a game changer for us with injection time. I can’t thank PetTest enough for providing them in their store !!!!!

    These are the best syringes I’ve used for my little Yorkie. He has been diabetic for 6 years and these seem easier for him to handle and me as well. Glad a dog friend shared the news with me. I’ll use them as long as Boomer needs them!
