Why Is Rhubarb Bad for Dogs?

Rhubarb is bad for dogs primarily due to its high oxalic acid content. Oxalic acid can bind with calcium in the body, leading to a dangerous drop in calcium levels. This results in symptoms such as muscle tremors and kidney damage. The leaves of the rhubarb plant are particularly toxic, but the stalks aren’t safe either.

How Much Rhubarb Can Dogs Eat?

Ideally, dogs should not consume any amount of rhubarb. Even a small bite can pose serious risks due to the toxic compounds present. If your dog has ingested a piece of rhubarb, it’s essential to seek veterinary help immediately to mitigate potential health risks.
