Rattlesnake season has started early here in San Diego and that means it is time to be extra vigilant when walking your dogs. If you are walking trails with deep grass and lots of rocks where snakes can hide, keep your dog on a leash and make sure you know where he is at all times. Dogs are curious and you don't want him putting his nose or paws in the hiding place of a rattler.
When hiking, be sure to have a first aid kit handy in a backpack and your cell phone with you in case your dog gets bitten. Also, make sure you know where the nearest emergency veterinary clinic is in relation to where you are hiking so you can get your dog there quickly if necessary.
Outdoor kitties are also at risk if you live in or near a canyon, so I would suggest they be kept indoors or supervised when outside.
There are snake vaccinations available if you are worried about possible snake bites. They will buy you some time to get to the emergency clinic if your dog does get bitten.
Best advise is to avoid hiking or walking in deep grassy areas at dawn and dusk. Also, make sure your legs and feet are completely covered. Stay aware and focused so you don't accidentally meet up with a diamondback.
