During an emergency, time is of the essence and it is best to go quickly to the vet, who treats your pet, or the nearest veterinarian. Although cannabinoids, such as CBD, are not toxic, there may always be the possibility for an animal to have an allergic reaction to one of the components.
When you go to the veterinarian, explain to him what exactly you have administered and in what dosage or what your pet has ingested, so that the vet can have a clear idea about what is generating that reaction.
