How is Hibiscus Poisoning Treated in Dogs?
If your dog is displayed the said symptoms of hibiscus poisoning – especially when you have got a hibiscus plant around – you should immediately take your dog to the vet. It is not advisable to try out home remedies in this situation.
Indeed, it would be helpful if you take along a sample of the hibiscus plant you suspect your dog has eaten to the appointment with the vet. This should help your vet better ascertain how severely – or mildly – the toxicity could be.
To accurately analyze the extent of damage done by such hibiscus ingestion, the vet could carry out tests on your dog’s blood along with a detailed physical inspection.
The latter inspection could include your vet checking the dog’s temperature, breathing sounds, body weight, pulse, blood pressure, and the conditions of its coat and skin.
Aside from your dog’s blood, the specialist could have to examine your dog’s feces and urine. This would help the vet determine if parasites or infections – instead of hibiscus poisoning – are responsible for the noticed symptoms.
In most cases, when examined by the microscope, pieces of the hibiscus plant could be present in the dog’s stool if really hibiscus poisoning is the cause.
Also, if you can, provide the vet with your dog’s medical records. Such provision is essential if your dog has been on some medications due to any recent ailment.
If your vet confirms your dog is experiencing hibiscus poisoning, the next four steps will be necessary in the following order: evacuation, detoxification, medication, and observation.
Starting with Evacuation
The vet could have to start with clearing your dog’s stomach. This is achievable by induced vomiting. Beforehand, your vet would have to administer peroxide solution to your dog.
This could be followed by oral administration of activated charcoal. The latter therapy is to absorb the left fraction of the toxicity from the eaten hibiscus.
Next is Detoxification Proper
Detoxification, in this instance, involves extensively flushing your dog’s kidneys. Intravenous fluids could be deployed here, especially as the vet has to prevent your dog from getting dehydrated due to diarrhea and vomiting.
It is Time for the Medication
After evacuation and detoxifying your dog, you can roll in the drugs. Medication is necessary when your dog suffered external burns (admittedly rare). Commonly, the vet applies lotion, with these being followed by a thrice daily application of that lotion when you take your dog home.
If the dog experienced internal blisters – predominantly in the throat – your vet might have to give your dog a cortisone injection.
Lastly is Keeping Your Dog Under Watch
After the preceding three phases of treatment, you have to carefully observe your dog and see how it reacts to the treatment. You would have to choose between leaving your dog with the vet for a while or bringing your home. Should you opt to take your dog, ensure you diligently collaborate with the vet on how well the symptoms are subsiding.
Why Do Dogs Eat Hibiscus Flowers?
Being deciduous shrubs, hibiscus plants are pretty conspicuous. Add this to their charming trumpet-shaped flowers and colorful leaves, and you see a plant that attracts at first sight.
Dogs don’t have the greatest discernment powers and could readily mistake the hibiscus flower for a snack. Too bad, your dog, by its very nature, happens to be a curious being.
This means it would be itching to check out the hibiscus flower in the yard. Even after sniffing it, your dog’s curious nature could push it into eating the hibiscus flower.
Given how the vast gamut of hibiscus flowers – some toxic and others non-toxic – are, the best wisdom would be keeping hibiscus plants off your garden or away from your dog. This way, you will significantly reduce the risk of hibiscus poisoning.
