My vet is adamant that chihuahuas, and a couple other breeds, ALWAYS wear harnesses instead of collars. If you will feel the front of your chi's throat, you'll very easily feel the trachea. It is waaaay too near the surface, exposed and fragile in chihuahuas. The pressure of a collar on the trachea, not to mention the added pressure of a leash tug, can damage or collapse the trachea.
There are wonderful, inexpensive and tiny harnesses available at www.cetaceacorp.com. I love these harnesses because they don't touch the neck, and are step-in harnesses with only one click-in fastener. They're fantastic. Anne " Lets talk about our wonderful little friends!
