My dog Jax just turned 19. He's gotten slower & I'm sure he has aches & pains. I gave him his first CBD cookie & he slept like a baby. When he woke up I could tell he felt better. He was playing with Hedgie (his stuffed hedge hog) and ran out the door when it was time to potty. He seems pretty darn comfortable! I have already placed my second order for more cookies. Love this product!
