My dog got two partial Frontline doses. Is it safe or should I wash?

I would wait two weeks, then apply the new dose onto Wellington. Even if you think you are giving half a dose, it may be more than that, and while Frontline is safe, too much can and does cause problems. It will be safe to give him the correct dose in two weeks. I hope this helps!

Keep an eye on Juno for signs of flea treatment toxicity including diarrhea, vomiting, excessive drooling, difficulty breathing, muscle tremors, weakness, and falling over. If you see any of those signs, take her into a vet immediately. Wash her now to get the flea treatment off of her.

No this is not something i can recommend, i strongly advise switching to a different product as well because frontline is not that effective anyway, i would recommend Advantage spot on, but you must buy the correct weight because if you use a product for a smaller dog it will not work.

The active ingredients in Frontline Plus are rather safe, so I would not be worried about any toxic effects this long after you applied the previous dose. Considering the bathing likely did remove a fair amount of the previous solution and you are seeing fleas, it's safe to say that Maddie will need some extra protection. The manufacturer recommends not bathing until 48 hours after applying Frontline, but I always advise not to give a bath one week after applying topical medications like Frontline to be safe. To be extra safe, you can get a different product prescribed by a veterinarian. I hope that helps and all is well with Maddie.

One drop from the dog's vial of Frontline shouldn't be a problem. The concentration is often the same, just the volume applied is more for a dog. Keep an eye on her just to be safe but she's probably fine. If she does show any signs of sickness, refusal to eat or drink, lethargy, drooling, vomiting, etc., get her in to your vet or an emergency clinic right away.

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.

Yes it is safe to reapply most topical flea preventatives every 2 weeks if needed. This should be fine and safe to do since you are 2 weeks out. However, if you are still seeing fleas after this correct dosing, it is best to consider switching to a more effective product such as Revolution. Best of luck with your cats moving forward and keeping the fleas away. Take care.
