Again…how toxic must this stuff be?! A dog might be young and healthy enough to take it with no adverse reactions for awhile, but it hasn’t been out long enough to know what kind of long term damage it may cause and I certainly wouldn’t give it to an old or ailing dog. I don’t need a study to tell me that. Comfortis killed my dog and I’ll never get over that.
This reminds me of our doctor telling my husband that he could take Vioxx and Prilosec forever with no problem. Riiiiiight. Good thing he has a wife who finds alternatives to drugs.
Seriously, if it’s toxic enough to kill fleas what’s it doing to your pet?
