So, my dog ate a popsicle stick....

No, but I dropped $1200 on my Rhodesian Ridgeback earlier this year for treatment of a stomach ailment the vet said may have been caused by 'stress'.
Stress????
The only worry in this dog's life is if his next meal is going to be 5 minutes late! He's the biggest 92-pound 3-year old couch-potato you've ever seen.
Stress! Ha!!!

Hope all turns out well with your dog and you're able to head to Florida. Dogs can digest almost anything as long as it's not poisonous like chocolate.
