Summary
Marathon County's zoning code sets no cap on dogs a resident personally owns, but boarding, breeding, or training seven or more dogs over six months old, for pay or belonging to others, turns the property into a regulated kennel.

Full Breakdown
The county's kennel definition is triggered at seven or more dogs over six months of age, but only when those dogs are not owned by the property's owner/occupant, or when the boarding, breeding, raising, grooming, or training is done for commercial gain. A qualifying kennel or pet boarding facility must then meet § 17.204.07(B), a minimum five-acre parcel, enclosures set back at least 100 feet from any property line, and noise/odor controls, and is only a conditional use in the county's C, B-R, and L-I districts. This is county zoning, so it applies only in unincorporated towns that adopted the Marathon County Zoning Code, not inside Wausau, Mosinee, Rothschild, or the county's other cities and villages.
Violations & Fines
Operating a kennel or pet boarding facility above the seven-dog threshold without the required conditional use permit and site standards is a zoning violation.
