Getting ready to take a trip to Florida. We are worried about our 4 year old V getting a hold of one of those poisonous frogs. We are thinking about a good muzzle for him while we walk him. Any suggestions on what type and where to buy a good muzzle???.....we live in Ohio and he has free reign over our 10 acres....as you all know, they love to explore and eat anything they find!!!!.....we will be staying with family in the burbs,,,,,a few trips to the beach too. Thanks!!
