Onions and Garlic
Your dog will have to eat a lot of onions and garlic to experience deadly symptoms. But like anyone who’s ever seen their family pooch wolf down a whole chicken, dogs can eat a lot in a matter of minutes. Concentrated forms of onions and garlic, such as dried onions, are a huge no-no. Onions and garlic contain compounds that can damage dogs’ red blood cells. However, the resulting damage isn’t noticeable for about three days. If your dog is affected, it may be unusually fatigued or have reddish urine.
