I think it is up to the owner if you decide to use it or not! A friend of mine was using CBD products to help their dog with epilepsy and it had helped. I have also heard things about it helping with arthritis in dogs as well. It couldn't hurt to try it and see if it helps your dog!!!
CBD can have quite good effects on calming anxious dogs, relieving pain, and possibly for seizures.
But it can also slow heart rate to a dangerous level, especially for small dogs with large doses given. I have discussed this with my vet and she said she has seen some worrisome issues with small dogs but has not, as of now, seen issues with larger dogs. She agrees that it can help, but that a test dose should be used when an owner can observe and take for vet care immediately if the dog shows any signs of lethargy, breathing issues etc.
It is currently an unregulated supplement so the dosage from any given supplier is a trust based on their lab tests provided. There may also be legal issues (U.S law) depending on state and the form of the product.
Dog's have the same Endocannabinoid system that humans have, it controls inflammation and ultimately helps balance your dog's natural cannabinoids. I tried it with my last dog who had epilepsy and it didn't really work for me. But I tried some CBD soft chews for my puppy to help calm him down on walks, and it helped out a lot. I also have a friend that tried CBD for her dog's anxiety and she also says it works well.
These are the soft chews I use for my pupper: https://elixinol.com/product/soft-chew-cbd-treats-for-dogs-sweet-potato-pie/
It definitely helped my old girl toward the end of her life (probable brain tumor), for which I'm grateful. I figured since she would be passing soon anyway, anything that helped her quality of life was worth using. It decreased the duration and frequency of her seizures and helped her sleep through the nights, which made a big difference in her mood and cognition.
Our vet recommended CBD capsules for my boyfriend's little senior dog. It has helped a lot with her arthritis. Before giving it to her, she had a very hard time continuing on walks with us. Joint supplements were not working at all anymore. It is no miracle stuff, but she is now able to comfortably go on walks instead of pouting around the house. I think it's worth a try if pain or anxiety is what you are having problems with.
