help with dog allergy

[cassandra's mommy]

[QUOTE=cassandra's mommy]my poodle has developed a allergy that no one has seen before even the vet is having a hard time also. you never know when she'll break out. starts like a pimple then gets about the size of a quarter turns bright red with a awful scab (looks like hives with a scab) , she doesnt scratch or lick but you can tell its uncomfortable. please help thanks this is my first time on this so sorry about not being real good.

That sounds like a boil. I wonder if dogs get boils.
