Yeah the vet perscribed Clavamox to me today. He said as long as Toby is eating,drinking, playing, and not acting lathargic he should be okay. Our vet also said that it could take a few weeks much like bronchitis is in our bodies for a few weeks during medicine.
I've read on a few vet sites that Clavamox works well so we'll just closely watch Toby. The other 3 Yorkies we have aren't showing any signs of sickness. Beckham and Daisy get their update to Bordetella this coming up Wednesday (shot) and Asher had his nasal boretella and is doing fine. I asked the vet if we should seperate them at all now... he said no because they have already been exposed and if they are doing fine then its okay.
So now we are having him take the Prednisolone (he had an injection at the vets emergency off and is taking it daily now) and the clavamox. They said these two medicines should clear him up.

I feel more comfortable now but will be staying in during the weekend to watch him.
