The Sauk County Humane Society took in 2,080 animals in 2025. Animal control took 226 calls, handled 156 bite cases, and impounded 179 animals. To ensure we do not have to euthanize healthy, adoptable animals, 542 animals were transferred to other shelters and rescue groups.

$590,152 spent$265,363 earned by the program84% of program spendingWe assisted two individuals with veterinary services through the josh diehm memorial fund for $122 to help owners who have fallen on difficult times keep their pets, three programs have been in place since january 2012: pet partership, safekeeping, and a pet food pantry. These programs help low-income county residents who are temporarily unable to care for their pets or who have emergency pet food or housing needs. These programs are designed to help residents keep their pets rather than giving them away or surrending them to the shelter. In 2025, we assisted 56 individuals through these programs and 40 pets.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $647k to $1.5M (+137%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 14%. Grants only. Government contracts and fees sit inside program revenue.
68% of SAUK COUNTY HUMANE SOCIETY’s revenue is contributions — about as donation-reliant as the typical peer (74% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

the vertical line marks half of all grant income — 2 funders to its left
90% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund SAUK COUNTY HUMANE SOCIETY.
Largest funder’s share by year: 2018 100% · 2019 100% · 2020 65% · 2021 53% · 2022 64% · 2023 89% — diversifying over time.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $14k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
