Topic: Revolution

Question:Does Revolution treat demodectic mange as well as sarcoptic mange? Very itchy pup, now 8 months old. vet had no evidence of mites first scraping so thought maybe sarcoptic. Have tried allergy testing. Ready to head back to vet as I cannot find any listing the revolution will treat demodectic mites. Thanks

Answer:The newer flea and tick products help more with Demodex: Nexgard and Bravecto. Revolution is not labeled for demodectic mange although, as an ivermectin derivative, probably does help it.

Topic: Tea tree oil

Question:Could u please tell me how much tea tree oil do I mix with water for my 2 lol yorkies

Answer:It entirely depends on the concentration of the product and since tea tree oil can be toxic to them, I only recommend using products developed for (and tested on) dogs.

Topic: Dog with mange.

Question:Hello, I have a 7 month old Bernese Mountain dog. She was just diagnosed with Demodectic mange and prescribed Cefpodoxime 200 mg along with shampoo and Simparica. Her condition seems to be getting worse more say then better. Is there anything else I can do for my 7 month old puppy to help the healing process?

Answer:Losing more hair shortly after starting treatment is not unusual but if it gets too bad, have your veterinarian recheck her - there are stronger medications but they have more side effects.

Question:My dog seems to be having some skin problems going on his fur is falling out in chunks and hes red and his ears are red and looks yellow and creamy inside

Answer:There are many things that cause of hair loss and redness (allergies, mange, hypothyroidism, ringworm, etc) and most are treated differently so have your veterinarian run some quick tests and make a diagnosis. Since allergies are the most common, here is a link to our article about various treatments for allergies, both over-the-counter and prescription: https://www.1800petmeds.com/education/allergy-treatment-dog-cat-9.htm

Topic: Puppy mites

Question:Hello my puppy has been scratching since I got him.The vet just diagnosed the puppy with mites. I have children and I wanted to know what precautions should I take and for how much time

Answer:There are 2 types of mites your dog can have - demodectic and sarcoptic - the first is not contagious at all to people so you wouldn't need to do anything, the second one is - it is called Scabies or Sarcoptic mange. Here is a good article about it written by another veterinarian, from a site that I trust: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951492

Topic: Scabies

Question:I acquired scabies as a human at a hotel I stayed at. I have since been cured of scabies. However I believe my cat may have some of the scabies mites on her. Shortly after I was cured of scabies, I was petting my cat and within minutes I got a bite on my wrist by a scabies mite. I have not petted my cat for about two weeks because I'm afraid that I may get reinfected by my cat. I don't see any sores or bites on my cat, but I've read that human scabies can live on a cat for a period of time. Should I take my cat into the veterinarian to get treated for scabies? I'm afraid I may get reinfected with scabies if I pet my cat?

Answer:All of that is very unusual : for a human to give a cat scabies more so and then for the cat to give it back. You wouldn't suddenly notice a bite from a sarcoptic mange mite - that sound more like a flea bite. So yes, have your veterinarian check your cat out to see what is going on and treat accordingly.

Topic: Demodicosis

Question:Hello I have a large breed Persian rescue dog which was diagnosed with Generalized Demodicosis, 8 months ago, he was prescribed antibiotics (metronidazole, Ciprofloxacin, and Coamoxiclave) and very frequent injections of ivermectin (1cc) every other day, plus multivitamins and omega 3,6,9, vitamin c+zinc, vitamin E, and Dr Clauder immune boost paste. Also he has been washed by Lindan and Permethrin Shampoos at least 15 times, and once with a henna solution(which really helped). Unfortunately, it keeps recurring and the foul smell and itchy skin cause him to scratch and make his skin bleed. I was searching for other treatments when I came across 2 topics: 1st) antibiotics aggravate demodectic mange?! (Small acne-like bumps-I was told they are folliculitis & I shouldnt worry) Mites are microscopic and live in hair follicles More common in dogs recently treated with steroids or antibiotics More common in dogs that are "rescues" or have been in stressful conditions Most common victims are under 3 years of age Dog may have a yeasty, musty odor or a yeast infection Allergy treatments didn't work or last) 2nd) Cheyletiella Symptoms Patchy hair loss Dusty hair with dandruff-like flakes Flakes may appear to move Mites are very tiny but may be visible occasionally Rough, unkempt, patchy-looking coat It's contagious other pets or people in the household may be itchy. He has both these condition, please help, should I continue giving him the antibiotics? Is it safe for him to tolerate Amitraz? Or Lime Sulfur? Any suggestions? Any products you would suggest? I have lab results, and photos too. Thank you for your patience with my long text. Im desperate please help 🙏🙏

Answer:Be sure you are still treating Demodex - like it needs to be regularly confirmed by a skin scrape at your veterinarian. Some dogs will have demodex when they are young and then (unrelated) allergies when they are older and people assume it's the mange coming back. If it is still Demodex, I would start him on monthly Nexgard and probably a lime sulfur shampoo and you may need to increase the ivermectin to daily, but only do that if your veterinarian rechecks him and recommends it. (Oh, antibiotics do not make demodex worse - that is an internet myth - steroids do though.)

Topic: Red mange

Question:My dog was diagnosed with red mange. Is this contagious to other dogs? Puppies in particular? Also is it possible for humans to get this?

Answer:No and No. Red mange is also called Demodectic mange which is not contagious (to other dogs or people). The other mange (Sarcoptic) is the one that is contagious.

Topic: dosage

Question:From this link... https://www.1800petmeds.com/education/mange-treatment-dog-cat-9.htm You said... "Heartgard, which is used at 6 micrograms/kg/month to prevent heartworm infections, is given at 100 times the heartworm dose (600 micrograms/kg/day) for 2-3 months to clear demodex infections. Treatment is continued until dogs have skin scrapings with no live or dead mites for at least a month." Is this .60 cc of Ivermectin per day for a 60 lb dog?

Answer:It would entirely depend on the concentration of the ivermectin and since this is off label usage, I can't recommend that you use that, especially because ivermectin at that dosage can be toxic to certain breeds(collies, border collies, shelties, australian sheperds, etc), so speak to your veterinarian about whether this might be right for your individual dog.

Topic: Democratic mange

Question:Is this a forever thing? Will my dog have to take medication for the rest of his life?

Answer:Usually not - especially if your dog is less than a year old - they usually just outgrow it. There is a very small % (probably less than 1% with the new, better treatment options) that will continue to have problems.

Topic: treatment for mange

Question:my pup is a rescue and about 10yrs old and although I haven't been able to afford a vet visit due to no money about to move and family with medical conditions I've done my research and I know my pup has sarpotic mange. I've tried countless over counter but she's clearly miserable and in pain.. I need something to help til I can afford vet visit. please. thank you

Answer:The new flea medications, Nexgard and Bravecto and Simparica help mange. They require a prescription from a veterinarian - if you go to your local Petco when their veterinarian is there, you have to wait in a long line but there is no office visit.

Topic: Essential oils

Question:If I dilute tea tree oil for cleaning and disinfectant for around my house is that safe for my cats? I will never directly put anything on them and dont use a diffuser but I want to cut down on the chemicals used In my house.

Answer:I actually wouldn't do that if you have cats. It would be hard to control the amount they might ingest if they started licking the floor, counter or wherever you cleaned.

Topic: Dog has mange

Question:I've been treating my 12 week old puppy for mange using shampoos for mange and a home remedy my dad always used of borax peroxide and water how long should it take to start clearing up also is there any other home remedies that are better than what I'm using?

Answer:There are 2 kinds of mange (demodectic and sarcoptic) and they are treated entirely differently so I will need to know more about your puppy to make a recommendation. Here is a link to treating Demodectic mange, the article is kind of old and doesn't mention some of the newer, better treatments but they are prescription so you would have to get them from your vet: https://www.1800petmeds.com/education/mange-treatment-dog-cat-9.htm

Topic: Red mange

Question:We just rescued a part Australian shepherd/ lab mix 6 months old in Alabama and took her to the vet and she has the red mange and was full of worms. He gave us medicine for the worms and she was heartworm negative thank goodness and gave us Heartguard and Nexguard and said the Nexguard would kill the mites causing the mange and is not contagious to humans or other pets. Is this correct and do you recommend a topical treatment along with the Nexguard to help treat this ?

Answer:All of that is correct and I usually start with just Nexgard. Some dogs will need stronger medication, but starting with just the Nexgard is a good plan.
