Game changer for my pet!

Finding these were a game changer for me and my pet. He used to flinch with the 29g with longer needle - but these - he does not even notice when I am giving him his injection. Happy pup - Happy Mom! thanks so much

Finally a Great Syringe for Pets

I had been using U100 syringes and converting the amount of Vetsulin to use as my dog could not tolerate the 29 g syringes the vet sent home. So happy to finally see this product! if I had any complaint at all it's that the syringe seems a little harder to push to inject than the ones I was using. Highly recommend these for Vetsulin users.
