Dog baskets are really only suited to smaller dogs, typically less than 20 pounds due to the need for you to feel balanced and able to ride safely. For larger pooches, you could consider getting a dog bike trailer so that they don’t miss out on the fun. But whatever size of dog or type of bike carrier, bicycle basket or trailer you opt for, the temperament and personality of your dog is key. Calm and positive dogs will love the experience, whereas the more lively, strong-willed or anxious pooch can make the experience much less enjoyable, for both you and your pet.
