Recently my Toy Poodle Oliver had a situation that arose very quickly and not even my regular groomer would touch it because she was afraid she might hurt him. She recommended that I take him to the vet. Out of desperation, I ordered the Fanny Foam. It took 3 seperate applications waiting 10-15 minutes each with a little bit of snarling and growling, but eventually the product loosened and dissolved things enough that I was able to get him cleaned up like it never happened in the first place. Now Oliver is as happy as a clam! This stuff really works, although in severe cases you may have to apply more than once and be patient! I will always keep a bottle handy now!
