Must have!

I have 3 Pet Shelties. Have to be so careful what they have by way of Heartworm and other drugs because of Ivermectin sensitivity. So many fancy products on the market now, uninformed pet owners can make the most dreadful mistakes.

Dimmitrol Heartworm Tablets

I have been using this product for many years and have found it to be highly effective for preventing any heartworm problem. While it is not always easy to obtain when needed, I have found the availability and pricing from Vet-n-pet to be first class.

Gets the Job Done

I prefer this method of heartworm treatment. I have three dogs and this is the cheapest way to do it. I also do it to continue the practice of the dogs taking and swallowing tablets, which they also occasionally have to do when receiving medication from the vet.

Reliable Product

My Labs don't particularly like the taste of heartworm tablets, but I have no problem giving them their one a day tablet by adding the tablet to a blob of margarine on a cheap water biscuit. They swallow the biscuit (with tablet) straight down.

Great product

Fast shipping. Unavailable locally so I was do happy to find this online. Thank you!
