Where can I buy heart work pills for a good price? Large dog about 30 pounds

You can purchase low-cost heartworm prevention at our (Spay & Neuter Clinic 2309 Chester St Fort Worth, TX 76103) but proof of heartworm testing is required. You must either show results of recent heartworm test, or proof of being on heartworm prevention. I hope this helps! Call 817 332 4768 x 112 for more info.

We get all our stuff at chewys

I like Chewy.com for my cat meds. Worth looking at their website. Hope this helps!
