Oregano Can Be Toxic to Dogs
According to the ASPCA, oregano can be toxic to dogs (and cats). However, this is a mild toxin to dogs. If your dog goes eat this, he may experience these symptoms:
- Vomiting
- Diarrhea
- Nausea
- Depression
- Gastrointestinal ulcers
In some cases, the herb has been known to cause low blood pressure, a decreased heart rate, or even ulcers.
If your dog only eats a little bit of oregano, he will be OK. This herb is only toxic in larger amounts. However, if your dog has eaten oregano and you’re worried, then be sure to call the vet. They will have the best advice and guidance about the safety of oregano for your fur baby.
