We use a stroller in some applications, but Kodi is not happy in one unless I am RIGHT beside it... Too much motion, even with the wheels locked, when they move around in it. Also, of course, it doesn't work for multiples!
For trials and shows, I use soft sided crates like Petgear. I MUCH prefer soft crates with zip-up ends to those with the spring tension rods inside. They may work well for big dog crates, but in small crates, they are VERY stiff, and I've gotten my skin caught in them too many times! Yes, you do have to be aware of where you put your crates. But that's true no matter what containment system you use. Don't be so sure that Nino won't start to chew on a soft sided crate just because he doesn't now. Many get "creative" once they hit adolescence. Panda is not trustworthy, so, although I have a soft sided crate for her when she gets older, right now, she uses one of my old collapsible Nylabone crates. These are great, BTW, if you can snag yourself one on Ebay. They are plastic, but have TONS of ventilation, and collapse down nicely. They are expensive, even though (or maybe BECAUSE!) they are no longer made. IMO, wire crates are the worst of all worlds. They are heavy to move around, and you still need to cover them to keep the dog comfortable and protected from other dogs. Virtually everyone who trials keeps their dogs covered. They want their dogs to relax and rest between runs. A lot of the trials I go to are small, one or two ring trials, where you can park pretty clase, and I just make a couple of trips to the car... First for my stuff, then for the dogs. At the big shows held at fairgrounds, where the parking is at a distance, I have a folding wagon that I use to transport everything but the dogs. I still have to make a second trip for them: Mac Sports Folding Utility Cart (WTC-109) - Lawn & Utility Carts - Ace Hardware
Remember that you also need a safe containment system for your car. Right now, a soft sided airline carrier attached to the seatbeltis fine.as he gets older, you'll probably want mething else. My choice is Ruff Tough Kennels right now. When I get a small SUV with a fixed back seaat, I will probably upgrade the a Variokennel, but they win't work safely with my current car.
From what I've seen, "show people" use different "conveyances" than people who trial. Trial people almost always use crates. Most use soft sided crates, and a few, whose dogs won't stay in soft sided, use wire crates with covers.
Show people, if they have a number of dogs, and are really into it, either have a trolley with wire crates stacked on it, or these really nice multi-cage comtraptions with wheels, handles and a grooming surface on top. All the show people I know with one or two dogs use Mardel Wonderwheelers with a grooming table built on top: Mardel - Grooming Tables, Ringside Tables, Carts and More!
. This gives you room for two small crates, your gear bag, and a grooming table, and you can wheel the whole thing in together. Most people use the plastic crates (they really do have adequate ventilation... The dogs don't get hot in them at indoor shows (I don't show outdoors
) but you CAN fit two of the smallest size wire crates on them instead.
