My 10 yr old labby has 2 cysts on his leg, a soft swelling on right side of tummy and a hard small mass under left side of belly. Last time I saw 2 vets they said to leave the cysts and the swelling was small - the vet is coming to check my horse so will ask him to look at him again. I've started to give him small amt every am of oil and every couple of days I rub salve on the cysts and swelling. The herbalist said I could use her cream or essential oil spray externally so I would appreciate any advice from someone who has used the oil internally - quantity daily? He is a happy boy runs around with my 2 yr old rescue collie/German Shep as though he was a young boy - could it be the oil? : ) almost certain it is .
