Can dogs eat garlic?

Dr. Marie replied:

It's a bit of an old wive's tale that Brewers yeast or garlic works to kill fleas.

Garlic can actually be toxic to dogs. It's possible that feeding a dog garlic may make it a little less tasty to fleas but it's not going to kill fleas.

I just did some searching for you as I never want to discount something just because I think that it's not true. I actually found a scientific study that was done to determine if brewer's yeast works for fleas. You can read the abstract here:

Does Brewer's Yeast Kill Fleas?

As you can read in the article the dogs treated with Brewer's yeast had no reduction in flea numbers at all.

I wish there were an easy and inexpensive remedy to fleas. If there was something that worked perfectly then we'd all be recommending it! One of the problems that I am seeing now is that fleas are getting resistant to many treatments. I blame this on over the counter pet store flea products. These products will usually only kill a percentage of the fleas. The fleas that remain then go on to reproduce and create a population of fleas that can resist cheap flea products.

The only products that I believe in are prescription strength products. These include:

  • Advantage <--You can buy this online without a prescription.

  • Revolution

  • Frontline <--You can buy this online without a prescription.

  • Comfortis
