Your pouch may need to be vaccinated. I'm no vet, (I am barely a DJ) but there is some sort of doggie disease going around that typically only dogs on the east coast get. They are commonly vaxed there for it too. Well, that disease has made it's way to the west and doggie's are getting very sick. I'm blaming planes. It's called Leptospirosis, which is a bacterial disease that can lead to kidney failure and even death.
Anyhow, look into it and see if your doggie needs a shot too. If you want more information click HERE
