Tea tree isn't soluble in water so you are giving your dog pure tea tree oil on it's skin, which is known to cause ataxia and other neurological symptoms. (those symptoms are reversible, but still...) And also not unimportant: most dogs hate the smell!! (and the warning with cats goes for all e.oils unfortunately, darn cat livers..)
Didn't here back yet CB, it was also a mixture with essential oils, she made a lot of money selling it at her stable last year

What I wrote before is how I learned it at my holistical medicine for animals course and paraveterinary training 17 years ago. I've worked in an animal hospital for years and we have never seen any problems. I know that lately there are discussions about the use of tea tree with a pro and con camp. I can only speak of my experiences and they are positive.
About the soluble in water issue: Barbara Fougere (President of the Veterinary Botanical Medicine Association, Australia) writes in her book 'Essential oils for flea control should always be diluted in water and then sprayed onto the coat... Alternatively, add 10 drops total (of one or more oils) to 20 ml of almond oil, and use 1 drop per kg of body weight by massaging into the coat twice weekly".
If you don't want to use tea tree here's another flea-free blend for dogs:
Place 4 drops per 5 kg of body weight onto a bandana daily, and 1 to 2 drops per 5 kg to the base of the tail.
Mix together:
- sweet almond oil 15 ml
- lavender 4 drops
- citronella 1 drop
- peppermint 5 drops
- lemon 3 drops
- clary sage 2 drops
Store in an amber bottle.
Some recepies for natural horse fly repellent:
Recipe from Mary Brennan, DVM, author of Complete Holistic Care and Healing for Horses: The Owner's Veterinary Guide to Alternative Methods and Remedies
1/2 teaspoon oil of myrrh
2 cups water
1/2 cup cider vinegar
1/4 teaspoon of citronella oil
Another one:
2 cups apple cider vinegar
2 cups cold (prepared) tea, such as sage or chamomile tea
20 drops eucalyptus oil
20 drops citronella oil
10 drops lavender oil
10 drops tea tree oil
10 drops cedar oil
20 drops emulsifier, such as polysorbate 20
And another one:
1 cup water
1 cup Avon Skin So Soft Bath Oil or Baby oil
2 cups vinegar
1 tbs. Eucalyptus oil
Optional: few tablespoons of citronella oil.
Shake spray bottle well before spraying on horse, human or dog!
If anyone has problems with flies in the barn, try filling a quart jar with this mixture.
3 cups of water
1⁄4 (one quarter) cup sugar
1⁄4 (one quarter) cup white vinegar
Mix, punch holes in the lid, and set it where needed. It works great.
Blessings,
