SportDOG Roy Gonia Clear Dog Training Whistle vs acme Dog Whistle 211.5 Frequency Black

Both options make for good, if unremarkable, Dog Whistles at the $8 budget range. While they should serve reasonably well, you might want to look into some other options at that price point.

If you're still interested in learning more about the SportDOG Roy Gonia Clear Dog Training Whistle and acme Dog Whistle 211.5 Frequency Black, however, we wrote-up what we know about them:

The SportDOG Roy Gonia Clear Dog Training Whistle hasn't managed to perform well enough to earn a place in any Dog Whistle roundups conducted by sources that do their own, high-quality, hands-on testing. That alone makes it a hard product to recommend.

Moving on to the acme Dog Whistle 211.5 Frequency Black: no sources that perform reliable and objective hands-on testing have included it in their Dog Whistle roundups, which usually means that a product doesn't make for a good purchase.

As a last step, we wanted to do a head-to-head SportDOG Roy Gonia Clear Dog Training Whistle vs. acme Dog Whistle 211.5 Frequency Black comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
