Always use harnesses, NOT collars
Never put collars on tiny toy dogs and lead them around with a collar like you would a regular sized dog. A collar can break their little necks or cause trachea collapse. Instead use a step in harness that does not encircle their necks. Most clothes for puppies have a harness built in. Please do not put a harness on your puppy until he is almost an adult as they are just not ready to be walked around when a tiny is in puppy stages. Yorkie Puppies have such tiny tracheas they sometimes make a snorting noise as they breathe. You can help by stroking their throats and the episode will soon pass.
