Allergies

Cooper, my GSD, was diagnosed with Hypothyroidism a few weeks ago, so my vet prescribed Levothyroxine, but he has been itching, scratching and licking his hair off

Cooper, my GSD, was diagnosed with Hypothyroidism a few weeks ago, so my vet prescribed Levothyroxine, but he has been itching, scratching and licking his hair off in places ever since. He is scratching so violently he is injuring himself. I had no choice but to take him off this medication to see if this is causing his allergic reaction. He also had extremely runny diarrhea when introduced to this drug. At this time I don't know if the Levothyroxine or possibly an inactive ingredient in the medication is the cause.

Chewy Rx price

Our older dog was diagnosed with a thyroid issue and our vet was charging $30 for a months supply. Chewy Rx price is much much lower and the auto delivery works

Our older dog was diagnosed with a thyroid issue and our vet was charging $30 for a months supply. Chewy Rx price is much much lower and the auto delivery works great. We have seen improvement on this med, which is most important and the huge savings helps us keep going with it.

I have been spending so much money on my dog’s medication at the vet for a couple of years! A friend looked it up for me and said they sell her meds and told me

Low Thyroid? These pills made a difference!

Stella is 15 and I do whatever I can to keep her healthy. When my Vet did a blood test and identified she needed B-12 and was suffering from hyper thyroid, he prescribed

Chewy's Delivery service left this box ON THE ROAD at the foot of my driveway

This isn't the first time that Chewy's delivery service has left my order where it can be exposed to weather, etc. Yesterday, my pet meds were left at the bottom

This isn't the first time that Chewy's delivery service has left my order where it can be exposed to weather, etc. Yesterday, my pet meds were left at the bottom of my driveway, IN THE STREET. EVERY other company I order from place my orders on the front porch, under the overhang. My driveway is barely two cars deep.... so maybe 20 feet. Really?!?! The delivery person can't walk a tiny box with one bottle of pills up to the porch? Again, this is not the first time. Buyer beware!!!!

Absolutely Outstanding Service in a pinch!!

I am on a trip and thought I had purchased the item to meet me at my destination- I did not confirm- my error- yesterday with one day left I checked and realized I had never completed the order. I promptly completed the order and moved on to other solutions which failed to pan out! I chatted with a technician on Chewy who had tried to help- I can only assume that she was able to do something because this morning I received a phone notification that the item was on the - holy cow! I couldn’t believe - and there it was on the front door step!!! Fantastic service, great price- forgot mention that if I had to buy from a local vet chewy was going to help with that price! Will order all the meds from chewy from now on!!! Thank you very much - Teddy

I didn't receive my order

I spoke to your representative & she said she'd put a rush order in on my replacement. I Called 1 week, called again, she was putting a rush order in & finally

I spoke to your representative & she said she'd put a rush order in on my replacement. I Called 1 week, called again, she was putting a rush order in & finally discovered you were out of my(Mel's) medication. She asked if I wanted a refund. I was so upset just hung up! Mel is my Service Dog, best friend & the only family I have! I'm a 100% disabled MARINE CORP Veteran. We live alone & she's everything to me!

Careful using this Tablet

Chewy sends out a disclaimer with each order of Thyro-Tabs. Unfortunately my dog shows two of the symptoms. Heat intolerance and heavy breathing. So I only use

Chewy sends out a disclaimer with each order of Thyro-Tabs. Unfortunately my dog shows two of the symptoms. Heat intolerance and heavy breathing. So I only use half the dose and then supplement with Kelp. Some dogs don't tolerate Kelp well in the gut but my dog does. Will know how well he is doing in his next blood check-up. I did notice his happier disposition and he is more energic with the kelp. I am truly glad Chewy took the step to notify its customers. My Vet had no idea of these issues I showed her the paper from Chewy. Its up to the owner to tell the vet if they see these symptoms and tell your vet or take steps to use something else natural.
