Both the water dispenser and the water bowl attached to each leash are made from silicone rubber and plastic, you won't need to worry about your dog being exposed to toxicity while ingesting water or food from either of these items.
Just as humans should stay well-hydrated while walking outdoors in the summer sun, dogs should too. Unfortunately, there aren't many public sources of water available where people tend to walk their dogs, so sometimes both dogs and humans end up going without. If you've got an Aqua Leash, you can use its bowl and dispenser to allow your dog to eat/drink.
You'll be able to get one of these leashes in a shade of red, black, or blue, so you can choose the shade you like best or the one that looks best on your dog. Alternatively, if your dog seems to have a preference for a certain shade, you might want to go with that one. If you've got more than one dog, getting leashes in different colors for them may also be a good idea.
