Meds seemed to work well

This is the first thing I ordered on auto ship from Chewy and it worked well. When my dog died it was easy to cancel it. I immediately received a confirmation email and some days later a bouquet of flowers and a sympathy card was delivered to us from Chewy. Amazing! We were so surprised. What company does that in 2025? Chewy.....that's who!!! Thank you chewy for your wonderful service these past years. If we get another dog we will definitely be ordering again from you!

Only one sensitive m schnauzer could take

Only one my miniature schnauzer didn’t have a reaction to. Although I have caught him sitting still trembling hours later or the next day for 5 minutes a few times

Only one my miniature schnauzer didn’t have a reaction to. Although I have caught him sitting still trembling hours later or the next day for 5 minutes a few times. I keep a closer eye on him when he gets this.

Tablets

Smaller and easier to give. Otis hates any medicine. Have tried all methods of giving it to him. He is very stubborn.
