Prof. Charles Hartman, Ph.D.Tarragon, like other herbs, contains estragole, which has a very different effect on dogs compared to humans. It's not poisonous or fatal, but, like many herbs, if a dog eats enough of it, it could upset their stomach. I've been cautious since my dog nibbled on some leaves and exhibited mild negative effects. My point is meant for any responsible pet owner who needs guidelines.
Keep an eye out for vomiting or diarrhea if your dog ingests tarragon. These symptoms usually occur within a few hours. Ensure fresh water is provided and intervene when necessary. My vet recommended not feeding my dog for a short period. In most instances, the issue remedied itself if limited to low doses.
Risk Factors
- Estragole Concentration: Higher in fresh vs dried leaves
- Dog Size: Small breeds face greater risk per ounce
- Health Conditions: Liver issues increase vulnerability
Preventive Measures
- Garden Placement: Grow in elevated containers
- Training: Teach 'leave it' commands consistently
- Supervision: Monitor pets near herb gardens
Emergency Response
- Symptom Threshold: Seek help for repeated vomiting
- Vet Information: Keep clinic contacts accessible
- Sample: Bring plant material for identification
Tarragon's relative safety is on a different level than that of truly poisonous plants. For instance, while plants like lilies or sago palms lead to organ failure, tarragon simply brings on more of a temporary inconvenience. Regardless, it's best to keep access to herb garden beds under wraps. I've actually built low fencing around the herb area just to be safe.
Provide non-toxic herb alternatives if your dog shows interest in your garden. Plant herbs like wheatgrass or parsley in an area that is easily accessible. This satisfies their urge to chew without ingesting any harmful plants. I have found my dog pays no attention to tarragon after I created a designated pet-friendly herb garden.
Discuss individual risk factors with your veterinarian as they relate specifically to your dog. Dogs with liver conditions will have additional considerations. You may want to provide fresh samples for your veterinarian to examine on your visits. My veterinarian appreciated having actual leaves in addition to the discussion of my dog's minor incident.
