Anybody used the Ortho brand. I put it on 3 of my dogs last night and about 30 minutes they were all going nuts scratching and whining. Its almost like it pissed off the fleas and they all started biting. I let this go on for an hour or so then gave them all baths and there fine now.
been using the Ortho max for about 2 years and it has eliminated my flea problem. also has twice the strength.
