Thank you both. I was a basket case last nite. I was pretty sure Rio would be okay as he seems to be the fittest dog on the planet but I was concerned about little Mignon as she is so little and young.And I really didnt want it running thru my house!!I am calling the pet store as these kids are 19 yrs old and after forking out all the money on such a poor breed example (she was sweet tho) now they have been faced with LOADS of vet bills. This is the second antibiotic the pup has been on so far
