Steps before going out can help prevent kittens or puppies from becoming nervous or fearful. First, place some toys or snacks in the sling and let the puppy play. This helps the puppy feel at ease. Second, lift the puppy 5 to 8 feet off the ground, soothe it with one hand, and walk slowly back and forth to help it relax. Third, place the sling on your shoulder and offer the puppy a snack to keep it calm. Finally, secure the safety lock to the loop on the vest or shoulder strap.Size Options for Chihuahua Carrier Bag The small size pet sling carrier supports pets up to 5 pounds.
