GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

While my puppy loved this bone and it was a good starter toy, it didn't last long. Our lab puppy loves to chew - especially when we stuffed the ends on this bone. After about 1.5 months of moderate use, she ended up chewing off and swallowing a small chunk of this bone, which she thankfully passed without issue. The material of this bone is intentionally softer than other kong toys, so it breaks down easier, and you will need to inspect it for wear more frequently. We have since upgraded to the large super chewer version for her, and she still loves it.
