Ugh parasites

So my dog is just over 2 years old. We have been treating her with this product since she was 3 months old. Sadly, today, in her stool, I noticed something white. Then I inspected the stool, and sure enough, there were worms. Some were moving. I contacted the company, and sadly, I was left feeling like I wasn't doing something right. Every month on the 18th with her breakfast, she gets this med. She also gets flea and Tick on the 11th. Along with treating our yard with diatomaceous earth to treat for flea and ticks. Fleas can transmit tapeworms. I just feel let down. I trusted this product.

Effective for French Bulldog

I have a 4 year old French Bulldog and switched to Frontline as the other medication was recalled and vet recommeded based on my questions and concerns. I personally prefer topical for flea and tick treatments. So far it has not only been affective but my pup has had no adverse reactions.

A works for my border collie

My border collie had a seizure and landed in the hospital after taking Simparica. Luckily he was ok after 24 hours but it was really scary. After doing some research we decided to try this. Thank goodness he hasn’t had a reaction in the couple of years he has taken this medicine. If you have a sensitive border collie(he has reactions to others as well) try this!

We recently moved and the new vet didn’t carry this, which our dog has been on for years and does well with. Chewy made it simple to put in the order and sent the request directly to our new vet to approve, and shipping was fast.

Must Taste Horrible

I struggle to get my dog to eat this. The only way I can get her to eat it is to chop it up really fine and mix it in her food. If it's not finely chopped, she spits it out every time and doesn't want to finish her meal. Even finely chopped, I wonder how much she actually ingests. You'd think they'd flavor this so dogs like it.
