my dog developed blisters on her muzzle. it also is swollen. I gave her Benadryl last night and noticed the swelling went down some.. not all of it, the blisters broke overnight and were red this morning. tonight when I got home her muzzle is all "scarred " and she lost her fur in that area. I cant imagine what she got into.. any suggestions?
Welcome! My name isXXXXX am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.

I am sorry to hear about this concern for Willow.
Well, it could be any number of things including having stuck her face into some type of plant causing a reaction. A insect bite or sting reaction is possible including bees and spider bites.

Benadryl is good to give and should be repeated.

Benadryl can be given at a dose of 1mg per pound of body weight. Keep in mind, Benadryl tablets and liquids come in different sizes. So, an approximately 25 pound dog can get a full 25mg tablet or a half of a 50mg tablet. I usually avoid the liquid Benadryl in larger dogs (you would have to give too much of it). You can give Benadryl every 8-12 hours.

But!
What you are really missing is a steroid shot from the vet. One of the fastest ways to resolve swelling and get a pet over a allergic reaction is a steroid, so that is well worth considering as soon as possible.

Also, instead of neosporin, you can apply a hydrocortisone cream for inflammation. Any over the counter generic hydrocortisone can be used.

Please let me know if there is anything I did not cover for you. I hope that information has been helpful.
