Dragon Snakes: Treating for Parasites
One of the biggest concerns that comes with all wild caught snakes is the potential parasite load they often bring. I treat all wild caught snakes for internal parasites within a week upon arrival, and I immediately treat external parasites if they are present, as well. External parasites are easy to detect and relatively simple to treat, and there are various online resources on how to treat them -- but the same cannot be said for internal parasites. Many inexperienced keepers that acquire a wild caught import believe the best course of action is to rush them to their veterinarian for an in-depth examination. Unfortunately, the stress they are put through as a result of the veterinary visit is often a major cause for decline and eventually death. When keeping wild caught snakes, it is crucial to avoid stressing them as much as possible, and this includes being poked, prodded and excessively handled by a vet. This is where experience comes into play. Knowing how to examine and identify potential issues with your snake and how to treat them without rushing them to the vet is extremely helpful in assuring the survival of such sensitive animals. In order to do so, I highly suggest establishing a good relationship with your herp veterinarian. I am able to treat all snakes for parasites at home because my veterinarian prescribes the medication via Telemedicine, allowing me to receive the necessary medication for my wild caught imports without having to put them through the stress of a long drive and physical examination.
Treatment for internal parasites includes an oral administration of Metronidazole (0.04mg/g) given once within the first week of arrival and then once more 2 weeks after the first dose. This medication is also effective against many strains of bacteria, and will also treat certain illnesses such as a respiratory infection. Since Metronidazole is typically prescribed in a 250mg tablet, it must first be dissolved in water to be administered to your snake. Your veterinarian can help you find the correct ratio in which you will dissolve the medication in, which will depend on the weight of your snake and dosage information provided above. For reference, dissolving one 250mg tablet of Metronidazole in 10ml of water would be administered at 0.04ml for a 25g Dragon snake.
I also treat each group of tadpoles for parasites a week prior to feeding them off. You can use Metronidazole for treating your tadpoles. I add 12 grams of Metronidazole per every 5 cups of water they are in. After crushing the tablet, use a high precision scale that measures in milligrams to measure out the correct ratio. Please reach out to your veterinarian if you are unsure on how to calculate the proper ratio.
