My dog swallowed cat fur

I have a 9 month old miniature jack russell that swallowed a wad of cat hair. I had been brushing my cat, and the cat hair was in the yard. When she got the cat hair in her mouth, we tried to get it from her and she swallowed it. She done this Saturday, and it is now Sunday and she still hasn't had a bowel movement. Does anyone know of anything that would help her pass this?

You could add a little canned plain pumpkin (not the pie filling type) to her food. :pawprint:

My chi x poodle just went through surgery to remove a large, dense hair ball from her lower stomach so if she shows any signs of nausea and vomiting then rush her to the vet.
