Hi, has anyone used pro meris duo flea treatment before.  My vet has changed from frontline combo to this as he says the frontline is not as effective any more.  Thanks in advance.

I use advocate on my bunch, i've always used this, i find that it works well and is very easy to use, it covers fleas, worms, mites etc. One spot on the back of the neck once a month an all sorted! :-)

No I haven't, however after another Malamute owners dogs all had a reaction to it I won't be trying it either.
