Well, I quit using them years ago and cannot remember specifics.What happens when you apply topicals to them? What brands are you applying?
But, shaking, foaming, and an allergic hive reaction on two of my dogs at separate times. One was a brand anyone can get from the store (which I have since read was a problem brand) and the other was actually a topical flea and tick product from the vet. I used it once and had to wash my dog and then take them back to the vet for the allergic reaction. Both products affected different dogs, but not in the same way. So, I just swore them off. I use interceptor chewables for heartworm and bravecto for fleas and ticks now.
