My Dog Keeps Scratching Itself And Has A Sore Mouth Which Is Swollen And She Keeps On Rubbing It On Her Bedding. She Also Does Not Eat From Her Bowl But Will Feed By Hand And She Seems Very Hot All Of The Time. What Maybe Wrong With Her. Thank You?

It may be an allergy, have you been able to look in her mouth to see if she has any swollen gums, or tongue,she may have eaten a bee or wasp and been stung in her mouth, I'm grasping at straws here, it's best to get her to the vet to be properly diagnosed and treated, she sounds miserable:(  best wishes.
