Is it safe to use flea treatment for a larger dog on my 71lb dog?

Pet's info: Dog | Labradoodle | Female | 9 years and 4 months old | 71 lbs

My choclate lab is 71 pounds. We purchased front line flea and tick for a 89-132 pound dog, is it still safe to use on the dog?

I wouldn't recommend using it on Sunny since she weighs less than the dose range. While dogs aren't as sensitive to flea treatment overdose as cats are, the potential is still there to cause toxic symptoms such as muscle twitches and loss of coordination. It's best to strictly follow the weight guidelines to prevent any toxicity from occurring. I would exchange the Frontline for a dose in her weight range.
