One more thing- I know we are discussing cannabis as cure, but I also work within the etheric body of people and animals. Sttones and crystals and tones are very good tools to manipulate this energy body on both humans and animals.
Crystals that are beneficial for dogs that are ill are Selenite ( water soluable, do not get wet), green calcite and bloodstone. by putting these stones in the dogs resting place it actually adds a vibration that requires the dog's energetic vibration to start to raise, as this happens the dis-ease starts to fall away into the background. Much easier to work with animals rather than humans who resist change and have firm beliefs.
Tones that work on dogs well are 396 hz and 417 hz. These should be done with weighted tuning forks and the tip of the tuning fork applied to the dogs third eye- in the area between the eyes. weighted are used because unweighted hurts the ears of the dog.These tones encourage the dog to return to it's natural homestasis- because animals rarely get ill without human involvement.
Crystal for sick cats- Selenite ( water soluable- do not get wet), green kyanite and Ruby. Placing these stones around where the cat sleeps or eats will help the cat to remember the 'greenman' energy for which cats are reknown for across the world. The energy of being independant of the influence of others. CAts need this to remain in a healthful state of homestasis.
Tones that help cats are in the 528 hz and 892 hz. These can be applied at the top of the head for a cat with weighted tuning forks, again the sound bothers the ears.
If you implement these crystals you will notice that your animals love them and will tell you what they want and how they want your help with them. I had a best friend for 19 yrs. that took her last breath curled around a very large quartz crystal and remains there in that stone to this day. Animals love crystals, they are part of the natural world that we have removed them from and help them remember what and who they really are.
Peace!

Oh p.s. as absolutely crazy as this may seem- attract as many frogs to the yard of sick animal as you can - the chirping that they do is mother natures natural medicine....
