My spaniel mix, Mindy has started doing something the last month which I can't figure out. In the backyard, she has started tearing out tufts of grass, shaking it and tossing it aside. She's not eating it, it's like she's hunting for something. It's not the whole yard but a large circle size area, basically my yard has a bald patch. She has always hunkered down in the grass and will stalk bugs in the yard but has never done this type of behavior. She seems fine otherwise and it's not like she doesn't have activities. I take her to doggie day care once a week and to a semi-wild park area where she can run and run. We play during the week when I get home so I'm not sure what is causing this. I've had her for a year now and she didn't do this last year at this time. Of course, I'm taking her to the vet for a checkup. My old girl before her never did this. She is obsessed with this! Has anyone seen this in their dog?
