Great advise everyone thanks a bunch. As for the food recommendation Sweetpea I think I'll look into the bison, it's actually cheaper than what we're currently buying and holistic I heard is a must. @Rural, we have had her on Benedryl and all that did was knock her out. The vet said it doesn't work on dogs too (whatever!) I believe it offers some relief.
A new vet is in order...
Okay, I know Benadryl and Zyrtec both work. I used them on Bullie when she was having terrible allergies to the weeds/grass in my yard (I gutted my yard out because of this dog...). So, in case you need to check your dosage - this is what I followed... Bullie is 60lbs so this dosage is for 50-70lb dogs:
Benadryl in 25mg capsules - 2 capsules every 12 hours.
Zyrtec in 10mg tablets - 1 tablet every 12 hours.
If your bulldog is under 50 lbs, you can use a once a day dosage.
Make sure the Benadryl is not a multi-symptom formula and make sure Zyrtec is not Zyrtec-D but just plain Zyrtec.
Okay, that said... Benadryl and Zyrtec are for allergies... that is, over-production of histamines. A yeast infection is the opposite of allergies - your dog is not producing histamines to fight the yeast. They give you almost the same symptoms but they are different. Yeast infection usually comes with a yeasty odor. Okay, an allergic dog that licks and gets teary could possibly produce yeast in the moist areas - this is external yeast and not internal yeast. So, your dog is over-producing histamines which causes the dog to itch and get teary so the dog licks and licks producing moist areas in his hair which is a nice beachfront condo for yeast. Make sense?
So, what I'm trying to say - observe your dog and see if this is truly an allergy problem or a yeast problem. Because zyrtec and benadryl will not solve a yeast problem - it could possibly make it worse. Also, the food adjustments you need to do is different between allergy and yeast infections. Yeast requires the least possible carbs/sugar in your dog's diet. Allergies is minimizing environmental triggers or changing up the protein sources.
Hope this helps.
