my vet says it needs to be removed, on my nine year old cocker, she licks at it. he says it contains histamines and to give her benadryl for it. he mentioned "mast cell tumor" he said its not cancerous. when i asked what it specifically was he either said AMENICIL or MENICIL. but i cant find any info on this anywhere. he said they''ll remove it and they are usually localized. anyone have any info about this? maybe the proper spelling? he said it so fast thats why im not sure what exactly it is. anything would be helpful. thank you.:(
