Overview
The DB900 is an ultra-light electronic training collar sized for small dogs between 5 and 15 pounds, sold as a two-dog set so one remote controls both collars. It offers beep, vibration and shock modes with a safety lock, and the housing carries an IPX7 waterproof rating.
MariMoki markets this under the 2026 Upgraded line, and the unit ranks in the top 250 electronic training collars on Amazon despite a modest 36 ratings. There is no seller description or review text to draw on here, so treat this as a spec-sheet read rather than a hands-on account.
- Fits small dogs 5-15 lbs
- Two collars, one remote
- Beep, vibration and shock modes
- IPX7 waterproof housing
Who it's for
Fits households with two small dogs that need a light, low-profile collar for basic beep and vibration cues. Owners of dogs over 15 pounds or those wanting a single-dog, long-range system should look elsewhere.
Strengths and trade-offs
Drawn from this product's published specifications.
- Set includes two collars and one remote for multi-dog households
- Beep and vibration options let you avoid shock for routine cues
- Safety lock guards against accidental correction
- IPX7 rating handles wet weather
- Sized only for dogs 5 to 15 pounds
- Just 36 ratings on record

Performance notes
The collar runs three correction levels, beep, vibration and shock, layered with a safety lock to prevent accidental activation. IPX7 waterproofing means it can handle rain and splashes, though it is not built for submersion.
