My little guy is always around other dogs and I use advantage on him every month since he was 10 weeks old. (They don't reccomend it for a puppy under 7 weeks.) It's a topical that you put between their shoulder blades and claims to kill 98-100% of fleas within 12 hours and keeps them protected for 4 weeks. My mother-in-law's dog had a infestation and everyone was getting chewed on. I applied some on her dog and the fleas stopped feasting when I called to checked 24 hours later. If you are in a location where you also have to worry about ticks, use advantix instead. The topical smells strong, more so with advantix. I reccomend you apply it to your dog just before a walk to give it time to dry and airout. Also, I was told by my vet not give my dog a bath until 7 days after. (He gets bathe frequently because he does therapy visits) This helps the topical protect longer. Psst.. I use to purchase advantage from my vet and pet store, but it's cheaper online. |
