Well the pills are based on weight. So if they are heavier right now, they should get a higher dose. If not, they could get heart worms. Also promotes drug resistance. So refusing you the wrong pills is the ethical thing to do.
Do you really want to spend all that ,only and stop short of doing it right?
*not a vet....but I asked one
They are based on weight,but when your dog is on the borderline weight it seems silly that 1lb is the determiner between efficacy and or resistance. Especially when in a 3-4 months that Same dog will be 1-2 lbs below the weight lines.
We get they have to have a cut off for warranty exposure and liabilities but in a practical sense, your 21 lb dog is no more at risk that when he is at 20 lbs.
Do what you want, but they do have cut offs for a reason. And in your case 2 lbs is 10% difference. When he is below at the time it is easy to do less. But go ahead and argue with the professional you are spending hundreds of bucks at for their professional knowledge. Talk about silly.
Actually when they are below that weight you can not do less as they are a single pill.
Here is their weight chart and dosage:

It is silly to think a .1 lb increase in weight needs about double the dosage than the 20lb dog. Especially when for 8-9 months out of the year the dog weighs less.
We can go round and round on this and neither will change our mind. If my boy dog was 22lbs + most of the year, especially during mosquito seasons I would probably get the higher dosage but he is the opposite and it doesn't make sense to spend an extra $100 for a 6 month supply that he will weigh too less for in 3 months.
