Measuring for an Infin8 Halter
By measuring your dog's muzzle & neck in the way shown below, you can select the correct size Infin8.
Use a soft tape measure
Place the tape across the bridge of your dog's nose and around the muzzle crossing it under the dog's jaw and then around to the back of the neck, to form a Figure 8 around the muzzle & neck.
Pull to a snug fit and write down this measurement.

Use your figure 8 measurement to select an Infin8 size.
| Measurements between 46 to 57cm (18 to 22½ inches) | Size 1 |
| Measurements between 53 to 68cm (21 to 26¾ inches) | Size 2 |
| Measurements between 60 to 77cm (23½ to 30¼ inches) | Size 3 |
| Measurements between 68 to 93cm (21 to 36½ inches) | Size 4 |
| Measurements between 76 to 107cm (30 to 42 inches) | Size 5 |
There are variations in muzzle shape between breed types, but the Figure 8 measurement should give you an accurate size selection.
Important: If your dog's measurement fits between 2 sizes, generally select the smaller size Infin8, unless you have a young, growing dog where the overlap between sizes is used to account for growth.
You can also use the chart below to select a size, but as there will always be variations in dog sizes, the chart below should only be used as a general indication, for best fit you should measure your dog (as above).
