PET SAFETY MONTH: 30 tips in 30 days that can save your pet's life - Tip #6
If your pup or kitty ate or inhaled marijuana bring him to the vet immediately and be honest about what happened so the vet can treat appropriately. Veterinarians are not required to report marijuana use and they don’t. Their concern is to treat. They can only treat approriately if you are honest and tell them what happened. Both dogs and cats can be affected by inhaling marijuana, but dogs are much more likely to eat, say, brownies with weed because like us they love sweets. Cats are obligate carnivores and do seek out sugar.
Note, as dogs and cats are much smaller than we are, the smoke cloud will be more toxic to them than to us. Be careful if you are indulging.
