Harnesses are a great alternative to traditional dog collars, especially for pugs with short noses, and miniature poodles, with their propensity for trachea injury, such as collapse, but it's important to make sure the harness fits your dog properly. Ill-fitting harnesses can cause injury to your dog, and make it difficult to maintain control. Measuring your dog ensures the proper fit.
The Right Fit
Using a measuring tape, measure from the top of the dog's breast bone - by feeling for the indentation there - around his neck, to the top of his shoulder. You'll easily feel the top of the shoulder bone at the base of the dog's neck. Run your hand down the back of the dog's head until you find the top of his shoulder bone. Take a second measurement from the top of his shoulder bone to the base of the tail. For the third measurement, place the tape at his breast bone and extend it to the tail by running the tape between the dog's front legs, along his rib cage to the base of his tail. Measure from the top of the dog's shoulder, along his side, to the last rib near his rear leg. Take each measurement two or three times for maximum accuracy, and note your findings. Record the dog's weight accurately, as this will also be a factor in choosing the right size harness.
