Unincorporated Yellowstone County sets no hard numeric limit on how many dogs or cats you may own. The county controls animals through its Dog Ordinance, nuisance rules, and Montana cruelty law rather than a per-household pet cap. Cities like Billings may impose their own limits.
The county's animal authority centers on dogs running at large, vicious dogs, and barking (MCA 7-23-2108 through 7-23-2110) plus state cruelty law, not a fixed household pet count. There is no county ordinance capping the number of dogs or cats a rural resident may keep. Excessive animals can still trigger nuisance enforcement or, at extreme levels, Montana's aggravated animal cruelty and hoarding provisions. Incorporated municipalities such as Billings set their own household animal limits, so residents inside city limits should check municipal code.
No county numeric-limit penalty exists; extreme cases are handled under nuisance or cruelty statutes (MCA 45-8-211/45-8-217).
