Can this be used if your fog has yeast in paws

is it help keep ticks and fleas off?
Answer by ChewyJan 12, 2022
In addition to being a rich source of the B complex of vitamins and protein, brewer’s yeast provides protective support against ticks and fleas. It will likely take a few days before you see a repellent effect from brewer’s yeast. This product should be given daily. Brewer’s yeast mixed with omega-3 oils may have a stronger repellent effect.

Is this good for dogs? Because I thought garlic is harmful for them
Answer by MountainMamaMar 22, 2023
It's very good for dogs. Garlic in small quantities isn't harmful. I give my dogs the maximum dose in summertime and they're fine. You can see bugs approach them and then turn tail and fly off.

Can you give this to cats too?
Answer by ChewyAug 17, 2023
This supplement is intended for dogs only.

Dogs Love them...

I give these along with a couple other supplements from chewy. Together I have noticed my dogs don't itch near like they normally do in the spring and summer. They lOVE these "treats" at least that is what they think they are getting. All 5 sit and wait their turn. This is the best bang for my buck. My fur kiddos are larger (Dalmatian) and they take 10 each a day. They like them so we will continue giving these.

Taste? but seem to work

I was ordering another brand, but that one was unavailable. The ingredients in this one seemed similar, so I got this one. It seems to work fine. My dog just doesn't like the taste of this one as much as the other brand. He will periodically just let it drop onto the floor and need coaxing to eat it which never happened with the previous brand. I will likely seek another brand next time for this reason, but nothing else particularly wrong with this one.

Dogs like them

My dogs like eating these 99 percent of the time, unfortunately, so far, I haven’t notice any benefits. The dogs are still covered in fleas. I will give it a little more time, and since they enjoy them, I will continue to give them to the dogs until they are finished. If they have no affect on the fleas, I will not reorder. I’m also using other products for the fleas as well, all at the same time, with no victories. I don’t want to give my dogs toxic treatments, but it’s beginning to look like there may not be any other choice.

Trying to return this order with no response!!

Placed this order and attempted to cancel with no response from customer service. Now that I finally received the order, I’ve been trying to return it. I’ve spent too much time on hold with no answer and no one has responded to several emails I’ve sent!
