If you're going to take a dog hiking, you should make sure that he is in the fittest condition he can be for being outdoors a lot! And part of that is to make sure he's appropriately vaccinated.
- Make sure your dogs' vaccines are up to date
- Does your area have Lyme disease problems? Make sure to get a Lyme disease vaccine.
- A de-worm medication can be good if giardia is prevalent in the area. It can help.
- If you don't want to over-vaccinate, don't worry about de-worming. Instead, be extra careful to filter all water before the dog drinks it.
Beyond that, check that your dog is wearing a rabies tag, has your contact info on her, and is free of any open wounds that are partial to infection!
