Hello. Delta probably has some type of allergy. I would start her on a good omega 3 fatty acid supplement such as Bayer's Free Form snip tips or Nordic naturals, both available at Chewy.com. This would be a good start & if it continues, please consider seeing you vet to make sure there are no other underlying problems or conditions with your pet. Thanks for using Petco Pet Education Center, formerly Petcoach.
