Entry requirements: bringing pets into Wisconsin
The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP, accessed August 30, 2026) requires a Certificate of Veterinary Inspection (CVI) for dogs and cats entering the state. Under ATCP 10 — Animal Health and Disease (accessed August 30, 2026), the CVI must be:
- Issued by a USDA-accredited veterinarian within 30 days of entry
- Include proof of current rabies vaccination (required under WI §95.21)
- Certify the animal is free of clinical signs of infectious or communicable disease
Wisconsin also requires that imported dogs be individually identified (tattoo, microchip, or physical description on the CVI).
Lyme disease: Wisconsin's biggest transition factor
If you're moving from a low-Lyme state (much of the South, West, or Southwest), Wisconsin's tick-borne disease landscape is a significant change. The Wisconsin Department of Health Services (accessed August 30, 2026) reports thousands of Lyme disease cases annually. Black-legged ticks carrying Borrelia burgdorferi are present across the state — not just in the rural north, but increasingly in suburban areas around Madison, Milwaukee, and Green Bay.
What this means for your move:
- Start tick prevention before you arrive. If your pet isn't already on a tick preventative (oral or topical), begin before the move — especially if you're arriving between April and November.
- Discuss Lyme vaccination with your new vet. Many Wisconsin veterinarians recommend the Lyme vaccine for dogs with outdoor exposure. It's a 2-dose initial series.
- Get a baseline tick-borne disease panel. Your new Wisconsin vet will likely recommend a 4Dx test (Lyme, anaplasmosis, ehrlichiosis, heartworm) to establish a baseline before your first Wisconsin tick season.
Wisconsin's winter: preparing pets for cold climate
If you're moving from a warm climate, Wisconsin winters are a genuine adjustment for pets:
- Temperatures routinely reach -10°F to -20°F in January and February, with wind chills below -30°F. Short-coated dogs need insulated coats for walks.
- Road salt and deicers are harsh on paw pads. Booties or post-walk paw washes become routine for many Wisconsin dog owners.
- Antifreeze exposure risk increases in winter — ethylene glycol is lethal to dogs and cats in small amounts. Store securely and clean spills immediately.
- Indoor air is extremely dry during Wisconsin winters (forced-air heating). Skin conditions and respiratory dryness are common in pets; your vet may recommend humidification or dietary supplements.
- Lake and river ice — Wisconsin has over 15,000 lakes. Dogs running on frozen lakes can fall through; keep them leashed near unfamiliar ice.
Dog licensing within 30 days
Under Wisconsin Statute §174.05 (accessed August 30, 2026), every dog over 5 months of age must be licensed. New residents must license within 30 days of establishing Wisconsin residency. The license year runs January 1 – December 31, with late fees typically assessed after April 1. Cat licensing is required in some municipalities (Madison, Dane County).
You'll need your pet's current rabies vaccination certificate to obtain the license. See our Wisconsin pet license application guide for city-by-city details and fees.
Finding a new vet in Wisconsin
The Wisconsin Veterinary Medical Association (WVMA) (accessed August 30, 2026) provides a vet locator. When selecting a Wisconsin vet:
- Ask about their tick-borne disease protocol — a good indicator of how tuned in they are to Wisconsin-specific risks
- Confirm they can receive your pet's records electronically
- If you have a senior pet or one with chronic conditions, ask about referral relationships with the UW-Madison School of Veterinary Medicine (accessed August 30, 2026) — one of the top veterinary teaching hospitals in the country
