Side by side with your four-legged friend! You would like to be active with your dog and do long laps and tours with him, but still not exceed his stress limit and protect his bones and joints. Especially puppies/young dogs, dogs with physical disabilities or four-legged seniors should be given a break in a bicycle trailer on longer tours. That's what he's for TAXXI DOG M is the right choice for small to medium-sized dogs. The Trailer with suspension provides a high level of comfort for the four-legged friends. Pets love it!
