No independent evaluator publishes an official list of the worst animal charities, but CharityWatch does publish its lowest grades. In an October 2025 report it named nine animal charities it rated D or F, with SPCA International, Paws of Honor, Dreamchaser PMU Horse Rescue & Rehabilitation and Front Range Equine Rescue at F. Each spent less than half of its cash budget on programs, and three spent $70 or more to raise every $100.
The table lists every animal charity in CharityWatch's October 21, 2025 report Animal Charities: Ratings Versus Reality. Grades are based on fiscal 2023 finances unless noted. "Program share" is the part of cash spending that went to programs after CharityWatch's adjustments; "cost to raise $100" is what the charity spent to bring in each $100 of cash donations. The Charity Navigator column shows the star rating CharityWatch reported alongside its own grade in the same article.
| Organization | CharityWatch grade | Program share | Cost to raise $100 | Other issue CharityWatch documented | Charity Navigator (as listed Oct 2025) |
|---|---|---|---|---|---|
| SPCA International | F | 21% | $78 | Its 2023 Form 990 reports paying $7,639,134 to Innovairre Communications for direct-mail strategy and $1,223,261 to PEP Response for marketing. CharityWatch has rated it F every year since fiscal 2009. | 3 stars |
| Paws of Honor | F | 16% | $74 | "No-risk" fundraising and consulting contracts tied to direct mail; its audit notes a potential future liability of $2,519,337 under them as of December 31, 2023. | 2 stars |
| Dreamchaser PMU Horse Rescue & Rehabilitation | F | 28% | $70 | The executive director owns the land where all operations take place; the charity paid her $42,000 in rent in 2023. | 1 star |
| Front Range Equine Rescue | D, downgraded to F | 43% | $24 | Downgraded because it held about nine years' worth of available assets in reserve. | 4 stars |
| Tiger Creek Animal Sanctuary | D | 40% | $37 | About 67% of total revenue came from one professional fundraising company; several related-party arrangements. The sanctuary disputes the rating (see below). | 1 star |
| Project K-9 Hero | D | 47% | $50 | None beyond the ratios | 4 stars |
| Redwings Horse Sanctuary | D | 47% | $31 | None beyond the ratios | 2 stars |
| Pilots to the Rescue | D | 47% | $30 | None beyond the ratios | 4 stars |
| Tiger Haven | D (fiscal 2024) | 43% | $36 | None beyond the ratios | 3 stars |
A D or F from CharityWatch is a judgment about financial efficiency, not a finding of wrongdoing. None of the organizations above was the subject of a regulator action in the sources we used.
Animal causes raise a lot of money through emotional direct mail and phone appeals, and that is where most low grades come from. The patterns in CharityWatch's report fall into a few groups.
CharityWatch treats a charity as highly efficient when it spends $25 or less to raise $100. The BBB Wise Giving Alliance standard is looser: fundraising should cost no more than 35% of related contributions. SPCA International ($78), Paws of Honor ($74) and Dreamchaser ($70) were far past both lines in fiscal 2023.
Some charities hand their fundraising to outside firms for years at a time. CharityWatch notes that SPCA International signed a ten-year direct-mail contract in 2006 that then renewed each year unless cancelled, and in August 2023 a three-year contract with a new vendor that renews automatically in one-year terms. "No-risk" contracts, like the ones Paws of Honor uses, mean the charity pays the vendor only out of money raised, but unpaid costs can follow the charity if the contract ends.
Accounting rules let a charity book part of a mailing or phone call as a program expense when it includes "education," such as facts about animal cruelty. CharityWatch moves those "joint costs" back into fundraising before grading. That is the main reason a charity can report a healthy program percentage on its own tax form and still get a D or F.
CharityWatch's highly efficient benchmark is 75% or more of cash spending on programs. The BBB Wise Giving Alliance asks for at least 65% of total expenses. Every charity in the table above was below 50% by CharityWatch's count.
CharityWatch lowers a grade when a charity holds more than three years of its budget in available assets and drops it to F at five years or more. Front Range Equine Rescue was downgraded for this reason. Related-party leases, licensing fees and payments to board members' family are not illegal, but CharityWatch flags them because they put insiders on both sides of a deal.
Grantmaking is a legitimate model; PetSmart Charities is a grantmaker with an A+ from CharityWatch (see best animal charities). The question is how much of what you give reaches the groups doing the work, which the Form 990 grants schedule (Schedule I) shows.
State attorneys general register charities and can sue those that mislead donors or misuse funds. If a charity you are considering has been sued or has settled with a state, the attorney general's press release or the court filing will say what was alleged and what was agreed. Treat a lawsuit as allegations until a court rules or a settlement is signed.
CharityWatch's report makes the point that other raters often score the same charities well. Front Range Equine Rescue, Pilots to the Rescue and Project K-9 Hero each had four Charity Navigator stars while holding a D or F from CharityWatch.
On October 13, 2026, Charity Navigator's profiles showed:
The gap comes from method. Charity Navigator's program expense ratio is a three-year average taken from the charity's own Form 990s, and its star rating combines that with other metrics such as governance policies and transparency. CharityWatch works from audited statements, moves joint solicitation costs out of programs, and grades on efficiency alone. Neither method is wrong; they answer different questions. If you care most about how much of each dollar reaches animals, the CharityWatch numbers are the stricter test.
Tiger Creek Animal Sanctuary published a response on its website. It argues that its D grade rests only on fiscal 2023 filings and does not reflect later changes, that CharityWatch's joint-cost reclassifications are hard to reconcile with its own audit and Form 990, and that efficiency ratios miss the long-term cost of lifetime care for big cats. It also says CharityWatch reviews new audits only on a two-year cycle.
SPCA International responded to criticism in a 2021 Mother Jones article. A spokesperson said the charity had made grants to more than 300 animal welfare organizations since 2007 and that its board had decided to keep working with its direct-mail firm.
A search on October 13, 2026 did not turn up published responses from the other organizations in the table. If one is published, it belongs next to the rating.
This is not a ranking. There is no reliable way to rank the "top 20 worst" animal charities in the U.S. One of the most-shared "worst" lists in search results is a Consumer Reports roundup from 2016, and ratings have changed since then.
