I'm new here and delighted to have found such a wonderful forum.
I have an urgent issue that I need more insight on I ask you to bear with me as I give the full details.
My Molly is almost 3 years old now. 1 year ago exactly, she started biting at her legs and butt a lot. I noticed that there seemed to be redness and raw sores where she was biting. She also was scooting along the carpet on her butt and then suddenly I noticed blood. She had a very large rupture that went through her skin beside her anus (anal gland rupture.) It was so infected that I rushed her to the vet emergency room. They drained it and cleaned it then gave us medicine for the infection. I asked about the biting and itching of the sores and they told me that it looked like a staff infection and the antibiotic should cure it. They thought the infection on her butt might have traveled elsewhere under the skin. I completed the antibiotics but noticed the biting and itching kept going on. Only now, she was making raw open sores and patches of hair around them would fall out. When they dried up, the skin would be dry and different and the hair wouldn't grow back.
My vet thought it might be a skin allergy but wanted to try 2 rounds of antibiotics to fully kill any infection first. Soooooo.....after 5 weeks, the infection cleared up but the hair never came back. Then, the sores came back and more hair fell out. By March of this year, her lower back, hips and hind legs and 1/2 her tail were almost hairless, the skin pigment was turning black, and her hair was thinning elsewhere too. Then the sores started coming back and her skin started scabbing up everywhere. In April, the vet tested for mites, fleas, and something else....can't remember. We did a second round of antibiotic therapy to kill off the infection again and then, as soon as it cleared, I changed her diet to a one protein source, minimum ingredient food to see if some kind of food caused this. I also considered insecticides/fertilizer from our yard, even chlorine from our pool. She has been bathed with Maloseb skin allergy shampoo for a year now. She had always eaten Merrick foods, LOVED Wing-a-Ling, but I always provided all their canned varieties with the dry. I switched to a dry, allergy formulated chicken dog food by Canidae? or Innova? for 3 months. Her infection cleared up again, but her hair continues to thin EVERYWHERE and now 3/4 of her body is almost bare. Her skin pigment blackened all over. Even where there is still some downy hair, it's thin and you can see the skin through it. Her ears have lost almost all the hair. Her tail is like a Jack Russels'. There are many areas where crust has formed around the base of each individual hair making it scabby. The slightest pull/combing of these areas makes her skin bleed immediately. Sometimes there is a "dusting" of tiny black particles all over her belly skin. It tested negative for mite poop. It's loose and flakey and the particles are as small as powdered sugar. 2 weeks ago, I changed her diet to an all raw, no grain diet at the advice of our natural pet supplies store. She is currently eating Stella and Chewy's Fresh from the Farm raw frozen lamb patties with a little bit of dry Nature's Logic Lamb formula. I also bought a new shampoo that is made up of mostly oils for skin allergies to put oils back into her skin. I alternate that with Maloseb. She currently has 2 spots she bites and itches and they are scabby. She also has started licking her pads deeply this past week. The rest of her skin and coat is just thinning and dying.
I'm so desperate.
My beautifully coated Havanese now looks mangy and sickly. The vet isn't sure what it is - she guesses allergies. I don't know how to get her coat back. Can anybody help? Has anyone had this happen to their dog or know of someone else's?
The pictures below show Molly 1 year ago before it all started, then this April, June, and then today. Thanks so much for your gracious time!
