I have been trying to avoid any ticka nd flea meds ( have been successful for the past 3 years with natural essential oi and shampoos. THis year, Mocha ( she is an Aussilear 4 years old ) started to chew on her tail ( she is on a raw diet of meat, ground bones organs ) she gets a daily salmon oil, just added brewers yeast daily and a little coconut oil . All of which was done after her problem. She has chewed a strip of her feather tail raw and yelps. We x-rayed her tail ( my husband is a chiropractor ) and it's not broken. She had gotten adjusted,and I have bathed her with good, healthy, nourishing shampoos. She still gets 3-5 fleas ( we flea com her 2 x day sometimes more. Im thinking she may be allergic to any flea bites. She will NOT let anyone touch her tail. I have a vet appointment next Wednesday. They will not give me the heartworm until she is tested. I am not wantign to give her teh flea meds but I dont know what to do . I have flea traps at the office and home and it is not showing any fleas in the house ( we do have carpet in the bedrooms . She does sleep wit us at night.
