I hate giving my dogs poison but of all the stuff on the market for the prevention of heartworm, this is what I found to be the best and with the least side affects.
And pet bucket, I first ordered a 12 month supply for both my dogs I received it in less time than I expected, so I then ordered 12 month supply for my son's 2 dogs and it was the same 2 weeks delivered.
Now iv been using simparica trio for 3 years, my vet would give us the same price I could get it online here in the us, cheapest I ever got it was like 400 per dog at pet bucket I paid less than that for both of my dogs. I was leary at first because the price, I got the product (no prescription needed) it was exactly the same.
It's like people prescription drugs , we pay 100 times more in the us for the same drugs in the uk
