Sent wrong med!!!

This was an order for three meds. Carprofen, Simparica, and Interceptor. You sent for carprofen but failed to send the interceptor and instead sent two Simparica

This was an order for three meds. Carprofen, Simparica, and Interceptor. You sent for carprofen but failed to send the interceptor and instead sent two Simparica. I wrote you about this, the reply did not address the issue, and then they canceled it without even telling me! So I have written you a second time and have not gotten any reply! I have been a client for a number of years but I am about to get rid of you! This is the second time in recent months that you have screwed up my order!

A Necessary Evil

Coby needs to take this but it is always a challenge since he will not chew it and always walks away from his bowl if I try to break it up and put in his food. Unfortunately,

Coby needs to take this but it is always a challenge since he will not chew it and always walks away from his bowl if I try to break it up and put in his food. Unfortunately, I'm always forced to break it into 4 pieces and push it down his throat. Any suggestions would be appreciated. Already tried peanut butter, roast beef and numerous other foods to no avail.

Items shipped by FedEx have arrived in a timely manner . This order ,for some reason ,was shipped twice via OnTrac . Both shipments never arrived ! Once I spoke

Items shipped by FedEx have arrived in a timely manner . This order ,for some reason ,was shipped twice via OnTrac . Both shipments never arrived ! Once I spoke to a Chewy supervisor, it arrived as expected . No surprise and no complaints ! Do not use OnTrac ! Even the post office staff have a very low opinion ! I have yet to hear anything positive . Thanks Chewy for fixing this !

I’ve been giving this to my 4-year old since he was able to take it. I have him tested for parasites and worms every year with his annual physical. He only goes outside when I walk him and in my daughter’s yard. I only feed him dog food, not table scraps, especially ham.

Something new.

I don't normally buy treats because my dog requires the vet diet products which is more expensive than many others. Initially, she turned her nose up at it but

I don't normally buy treats because my dog requires the vet diet products which is more expensive than many others. Initially, she turned her nose up at it but later ate it. She likes them now. I was expecting it to be soft treats but they were crunchy.

It works

Give monthly to prevent heartworms. Never miss a pill. It takes one infected mosquito to give your dog heartworms.
