Why there's no grade to give
Human CBD-and-sleep research is itself mixed, and in dogs nobody has run the trial: no actigraphy, no sleep-lab equivalent, no placebo-controlled nights. What exists is owner surveys — which is to say, hope measured in questionnaire form. We won't dress that up as science.
What night restlessness usually is
- Pain — arthritis aches worst after hours of stillness. This is the most missed cause in seniors, and the one place CBD has real (pain-trial) evidence.
- Cognitive dysfunction — sundowning in older dogs: pacing, standing in corners, day-night reversal. A veterinary workup, not a supplement decision.
- Under-exercise — an unemptied tank at 11 p.m. is a schedule problem.
- True anxiety — storm-phobic or velcro dogs whose arousal never drops. Here the daytime evidence at least rhymes.
If you trial it anyway
- Film two baseline nights first — you need something honest to compare against.
- Standard daily tier (1–2 mg/kg) with the evening meal, so peak levels land near bedtime.
- Hold everything else constant for two weeks, then re-film. If the camera can't tell the difference, there isn't one.
- Senior dog with new nighttime behavior? Vet first. Always.
