My 13 year old Rat Terrier has been has been taking homeopathic remedies from Dr. Jeff for the last year. I am very pleased how it is going. The issue I am seeking help with is a sebaceous cyst on my dog's lower chest. It has been quite small for about the last 5 years, less than 1/2". In the last year it grew larger to about 3/4". In the last week it has become the size of a small golf ball and part of it is red. About 6 months ago the cyst drained some, I don't know if it will drain again. The most recent remedy he took is Lachesis 30c, that was the end of May. Also for the last 3 weeks he has been taking LDCO to help with tick coinfections. Do you think the Lachesis or the LDCO could have any connection to the cyst becoming so large. I would appreciate any input on dealing with the cyst. His BEAM B-8, E-7, A-9, M-7. He is sleeping quite a bit, and a little clingy. I do not want to go to my local vet for this.
