Hello All,
My pup (4yrs.) Threw up 3x yesterday and 3 the day before. Today she threw up once at 6am but has not since. She is not throwing up any of her food just stuff that is frothy and clear/yellow. The day before I gave her flea and tick treatment and she also went to the groomers 2 days prior to that. Any ideas what this may be from. She seems like her old self again. I tried to get a vet apt. but was told that I could not do so for 2 weeks

Any ideas as to why she might be throwing up? Like I said she has not done so all day. Any OTC meds. I should give her?
Thanks
