Hello,
I tell my clients that when you buy from us (the vets) that you get a product and safety guarantee you are unlikely to find elsewhere. But I firmly believe that every vet should carry an assortment of preventative options to meet everyone’s budget. Ask your vet what they think is best. Ask for a price quote and then talk about the budget you are comfortable with.

Good morning?
We get our preventatives from the vet. I feel that they know what works best for or pets and the proper dosage, etc. And going to visit them every so often for pick up is good socialization for our dogs and helps reinforce to them that the vet can be a fun place to visit.
