Nexgard (24.1-60 lb.) 12-count
I have been ordering through Sierra Pet Meds for the last seven years and have never been disappointed. The ease of online shopping, earning rewards, free shipping (unless you need it sooner) and no need for a script makes purchasing affordable, easy and rewarding. Customer service is also very prompt. No complaints, and as a matter of fact, I have referred several friends and family who are also repeat customers.
