Nearly half of pet owners — 47% — think legal pet “co-parenting” agreements to split a dog or cat’s medical costs should become as standard as child support, according to Spot Pet Insurance’s 2026 “Pet Parent Perspective” survey of 4,150 pet owners. That’s not a fringe opinion anymore. It’s close to half the pet-owning population saying breakups involving an animal deserve the same formal paperwork as breakups involving a kid.
The same survey found 31% of pet owners say a partner refusing to pay for a $7,000-plus life-saving surgery would end the relationship outright — a sign that pets have moved from “shared responsibility” to something closer to a shared dependent in a lot of households.

The Law Is Already Catching Up
This isn’t just a vibe pet owners have picked up from social media. Actual family law has started moving in the same direction. California passed a law explicitly distinguishing companion animals from other divisible property in a divorce, directing courts to consider the animal’s well-being rather than simply splitting it 50/50 like a couch, according to the Animal Legal Defense Fund’s analysis of the statute. Alaska went further, becoming the first state to require courts to weigh an animal’s own interests when deciding custody in a divorce, per the Animal Legal Defense Fund’s coverage of that legislation.
That’s a meaningful legal shift. For most of American history, a pet was property, full stop — legally indistinguishable from a television or a car in a divorce settlement, awarded to whoever had the stronger ownership claim and nothing more. A handful of states writing “best interest of the animal” language into their statutes signals lawmakers are responding to exactly the sentiment Spot’s survey is picking up: pet owners increasingly don’t see their animals as property to be divided, but as family members who need an actual plan.
Why Money Is at the Center of It
The push for formal co-parenting agreements isn’t primarily about who gets weekend visitation. It’s about money, and that’s what makes the 47% figure make sense next to the rest of Spot’s data. Veterinary costs have climbed enough that 14% of pet owners admit to downplaying a vet bill to friends or family out of embarrassment, according to the same survey — a level of financial strain and secrecy usually associated with human medical debt, not a trip to the vet.
When one partner in a couple has been covering, say, insulin for a diabetic cat or ongoing treatment for a dog’s chronic condition, a breakup doesn’t just raise the question of who keeps the pet. It raises the question of who keeps paying — and without any agreement in place, that responsibility often lands entirely on whoever ends up with physical custody, regardless of whether the costs started as a shared decision.
What a Real Agreement Actually Covers
Family law resources that track pet custody cases note the agreements taking hold in practice tend to mirror child custody arrangements in structure, if not in legal weight: a schedule for time with the animal, a plan for splitting veterinary bills and pet insurance premiums, and a decision-making process for major medical calls, according to the Animal Legal & Historical Center’s overview of how courts handle pets in divorce. None of that existed as a standard practice a decade ago. Most couples simply argued it out or let whoever moved out first lose the dog by default.

Most Couples Still Don’t Have One
Here’s the gap worth noticing: 47% of pet owners think these agreements should be standard, but that’s an opinion about how things should work, not a report of how many people actually have paperwork in place before they need it. Most couples who move in together, adopt a pet jointly, and never discuss what happens to that pet if they split are operating exactly like couples did a generation ago — no plan, no agreement, just an assumption that it’ll sort itself out. The survey data suggests that assumption is increasingly out of step with what pet owners themselves say they want.
That gap between belief and practice is where the real risk sits. A couple that agrees in theory pets deserve a custody plan but never writes one down is in the same position as a couple with no opinion on the subject at all the moment an actual breakup happens. The difference between “we should have done this” and “we did this” only shows up when it’s too late to negotiate calmly — which is exactly the moment most people are worst equipped to negotiate anything.
The Real Shift Isn’t Sentimental — It’s Practical
It’s tempting to read all of this as pet owners simply being sentimental about their animals, but the data points somewhere more concrete. People aren’t asking for co-parenting agreements because they think a dog needs a lawyer. They’re asking because unpaid vet bills, unclear ownership, and no agreed-upon schedule turn an already painful breakup into a financial and logistical mess nobody planned for. Formalizing it in advance isn’t about treating a pet like a child. It’s about not leaving a five-figure medical bill and an animal’s care up to whoever’s angrier during the split.
