I've used tea tree for neutralizing my dog's odor. She's a small lg. dog; an Aussie/Lab mix, & I've used it for skunk odor also. You don't need much to get the smell out.
Don't use tea tree oil on small dogs!! by: Anonymous
We used it on our Westies and it caused severe paralysis. They couldn't walk for 12 hours. Researched it and tea tree has been know to cause problems with dogs imperticular.
