If your vet really said that a 3 year old dog can’t get mange she is crazy. However, it most likely isn’t mange anyway. With a terrier it is most likely an allergy. The best thing to start with is a bath to get all the spores and pollen out of his coat. Then a daily swim (do you have access to a swimming pool?) will help keep the pollen/spore count down on his body. Even a small kiddy pool would help. If you can’t get him swimming, then a daily rinse in a sink will help. If you are doing the sink/tub rinse try using 1/3 vinegar, 2/3 water – work it into the coat and skin and then let him shake and dry – don’t rinse the vinegar mix out. The vinegar helps reduce the itch and helps the skin heal.
If he has any raw spots, pat on some Witch Hazel with Aloe Vera (found in any pharmacy), it too helps with the itch and helps the wound heal.
Try Zyrtec instead of the Benadryl, it seems to work better – use the same dose the vet mentioned for the Benadryl.
Next, get all the grain out of this dog’s diet, that includes treats. No sharing bread crusts, cookies, or corn chips! Many terriers can not tolerate grains and this leads to allergic reactions – ear infections, chewed off fur, hot spots, etc. Go to a good pet store and ask to be shown to the grain-free dog food area. Then start reading the ingredients. You want to find a dog food that lists real meat (it will name the meat! ie. bison, pork, elk, lamb, salmon meal, turkey meal, etc) as the first 2 or 3 ingredients. Do NOT buy any dog food that lists “by products” as an ingredient.
It can take up to 3 months for a dog to grow a new coat – so it is way too early for you to see much hair on this boy, also he could have scared the skin with scratching to the point that hair won’t come back at all. But, don’t worry about that yet – it is too early so worry! I once cured a dog with terrible mange and she grew a lovely coat everywhere but on her tail – poor little rat tail! Then about a year later the hair started to grow! And in 30 days she had a lovely Cairn tail, just in time to be adopted to her forever home. I love a happy ending, don’t you!
Thank you for rescuing this boy – he is going to need TLC and a good diet to be all that he can be, but he will be worth it!
The signs of mange: terrible itching, on a scale of 1 to 10, mange is about a 20! Really – it is the most itch a dog or human can have! Look for little yellow puss filled bumps, or raised red spots, constant chewing and scratching, and him running his back and sides under tables and sofas, on the carpet, etc to scratch the itch. If this is happening, find a new vet to do a skin scraping (which may well be negative since you applied the flea stuff recently). The treatment is 3 dose of Revolution given 2 weeks apart. So if your dog is showing these behaviors, I would ask the vet for the Revolution and treat the dog for mange even with a negative skin scrape.
But if he does not show these behaviors, just wait – a good diet and the daily swim/rinse will work wonders.
Good luck!
Dogs bleed during only the beginning of the heat cycle. Usually longer than 2 days. She may be keeping herself so clean you don’t notice the blood. All my dogs do this.
