Olde English Bull Dog with skin problems

Question
I have a 6 month old Olde English Bull Dog with skin irritations.  When we got him he was 3 months old and perfect health condition.  Now he is red, itchy and has little white pussy bumps under his armpits.  He bites and itches all over.  We have changed food, gone holistic, spent a bunch of money on him but nothing seems to be working.  Any ideas on what it might be?  We have been told it was a yeast problem or an environmental problem.  So we ripped up all rugs in the house and put in hardwood, feed him out of glass bowls.  None of his siblings (there were 7 of them) have any problems!  Any suggestions???

Answer
Hi Chad!
Wow you guys really love your dog! I admire that!!  Have you had a Vet do a skin scraping?  There are different types of mange that can cause the itching and bumps as you describe. A Vet can also take some of the skin scraping and "grow" a fungus with it that can determine what it is.  You may want to check on that.   In the meantime, over the counter Benadryl is really good for dogs to ease itching.  Read the directions below carefully.
God Bless!

Benadryl for Dogs or Cats

Benadryl is a brand name for an anti-histamine (diphenhydramine).  Although it is considered fairly safe for use in dogs and cats,  please be aware that it does have potential adverse side effects.  It may interact with other meds that your pet is taking, so do not use it without first consulting your veterinarian. You should also use extreme caution using Benadryl in dogs that have glaucoma, prostatic disease, cardiovascular disease or hyperthyroidism.  

Benadryl is quite effective when used in proper dosages.

Be sure to use only the plain Benadryl formula. Giving benadryl with other combination of meds could be fatal, so be sure to read the box.

Liquid Benadryl is too high in alcohol content to be safely used for animals.  Please use capsule or pill form.
