My dog threw up from garlic flea control. Are her liver/kidneys okay?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua (Smooth Coat) | Female | spayed | 5 years and 10 months old | 11 lbs

My chihuahua was on Bug Off Garlic for 9 months. She started throwing up after meals so I stopped the supplement. She has improved since then. Is there a chance I hurt her internally by giving her that in the past. I was trying to do something natural and safe for her to repel fleas, but I feel like I made a dumb choice. She seems fine. I just don't want to have caused liver or kidney problems.

I'm glad to hear that Minnie's vomiting has improved since you stopped giving her the garlic supplement. At high enough doses, garlic can cause varying degrees of damage to the red blood cells and occasionally can affect the kidneys. Odds are good that Minnie is not experiencing any of these problems since her vomiting has improved since stopping the supplement. However, the only way to know how well her red blood cells and kidneys are actually working is to take her to the vet to have some blood work (a CBC and chemistry panel) checked. The important part is that you recognized the potential for problems and stopped the supplement - I highly doubt it caused any lasting damage! Unfortunately, there aren't any "natural" safe and effective flexible preventive options. I'd recommend talking to your vet about starting Minnie on a prescription chewable product, like Nexgard, Simparica, Credelio or Bravecto. Since fleas and ticks can transmit a number of different diseases, it is important to keep her on an effective product consistently. I hope that everything goes well for Minnie!
