Vinca plants, also known as periwinkle or running myrtle, are popular in gardens. They are beautiful, with pretty flowers that cover the ground. But dog owners must know that these plants are harmful to dogs. This article explains how Vinca plants can hurt dogs, signs of poisoning, and what to do to keep your dog safe.
Is Vinca Poisonous to Dogs?
Yes, Vinca plants are toxic to dogs. The ASPCA warns that all types of Vinca can harm pets. The most dangerous one is Catharanthus roseus, also called Madagascar periwinkle. Every part of this plant is poisonous, including the flowers, leaves, stems, and roots. Other types of Vinca, like Vinca major (greater periwinkle) and Vinca minor (lesser periwinkle), are less harmful but can still cause problems. It’s important to know which plant you have and keep your dog away from it.
What Makes Vinca Toxic to Dogs?
Vinca plants contain chemicals called vinca alkaloids, such as vincristine and vinblastine. These can harm cells, especially in the stomach and nervous system. They are also used in cancer treatments, but they are toxic to healthy cells, too. Vinca alkaloids damage cells by disrupting their structure, which leads to poisoning.
Other harmful chemicals, like daphnetoxin in Vinca minor, also contribute to toxicity. Although vinca alkaloids are the main concern, these other compounds add to the overall risk.
Signs of Vinca Poisoning in Dogs
If your dog eats any part of a Vinca plant, watch for these signs:
- Gastrointestinal symptoms: Vomiting, diarrhea, stomach pain, bloating, drooling, and loss of appetite.
- Heart problems: Weakness, low blood pressure, and irregular heartbeat.
- Neurological symptoms: Lethargy, lack of coordination, tremors, seizures, and even coma in severe cases.
Dehydration, trouble breathing, or difficulty swallowing may also occur. If your dog shows any of these symptoms, get help from your vet immediately.
How Serious Is Vinca Poisoning?
The seriousness of poisoning depends on:
- The type of Vinca plant: Catharanthus roseus is the most toxic.
- How much was eaten: More plant material means more toxins.
- Your dog’s size: Smaller dogs are more at risk.
- Your dog’s health: Dogs with existing health problems may suffer more.
If your dog eats Vinca, act fast. Getting help early is crucial.
What to Do if Your Dog Eats Vinca
If you think your dog ate Vinca, call your vet right away. Tell them how much your dog ate, what symptoms they have, and what type of plant it was.
Do not make your dog vomit unless your vet tells you to. Improper vomiting can be harmful. Bring a sample of the plant if you can, so the vet can confirm what your dog ate.
Diagnosis and Treatment
The vet will examine your dog and may run tests like blood work or urine tests. They might also do an ECG to check for heart problems. Treatment includes:
- Induced vomiting to remove toxins.
- Activated charcoal to stop toxins from entering the bloodstream.
- IV fluids to keep your dog hydrated.
- Medications to control symptoms like vomiting or seizures.
The vet will monitor your dog closely to make sure they recover.
Preventing Vinca Poisoning
To keep your dog safe, prevent them from eating Vinca plants. You can:
- Put fences or barriers around the plants.
- Plant Vinca in areas your dog can’t reach.
- Choose pet-safe plants like Impatiens or Star Jasmine.
Always watch your dog when they’re outside. Train them to avoid plants if they like to chew on them.
