Chino FAQ
How do I report a barking dog in Chino?
Contact San Bernardino County Animal Care & Control (the city's contracted provider) at (909) 386-9820. Document the dates, times, and duration of barking before filing.
How long can a dog bark before it's a violation?
There is no fixed-minute trigger in CMC. Continuous or repeated barking that exceeds 50 dBA L50 at night (or 55 dBA day) at the neighbor's property line violates CMC § 9.40.040, and habitual barking is independently a public nuisance under County Code.
Does the Inland Valley Humane Society handle Chino?
No. IVHS contracts cover Chino Hills, Pomona, Diamond Bar, Claremont, and several others, but not the City of Chino. Chino uses San Bernardino County Animal Care & Control.
Ontario FAQ
How do I report a barking dog in Ontario?
Contact Ontario Animal Services and submit a barking log with dates, times, and duration. Corroboration from another household helps the case move forward.
What counts as excessive barking?
Persistent or repeated barking that disturbs a person of normal sensitivity. Brief reactive barking at a trespasser or wildlife is not enough on its own.
