If something has just been eaten

• 🍫 How much chocolate is too much?How much of what kind, against the dog’s weight — and the mg/kg it works out at.
• 🍬 How much xylitol is too much?Gum, mints and anything labelled birch sugar. The dose is never on the packet, so this runs the range.
• 🍇 How many grapes are too many?The one-per-10-lb rule, worked out for your dog — and why the answer is the same either side of it.

Pet Poison Helpline's 2025 call log put chocolate first for dogs, then grapes and raisins, then bromethalin rat bait, then xylitol. Three of that top four are above. Bromethalin has no calculator on purpose: rat baits come in five chemically different types dyed the same colors, and the only number that matters is the EPA registration number on the box.

Heat

• 🌡 Is it too hot to walk my dog?Temperature, humidity, sun — and the dog, which usually matters more than any of them.
• 🚗 How hot is it inside the car?The actual curve from the Stanford study, and why cracking the window changes nothing.

Three quarters of the dog heatstroke that reaches a vet is caused by exercise rather than parked cars, and the average case happens at about 62°F. If it has already happened, cool first and drive second — the method most websites recommend is out of date.

Everyday

• 🦎 What does this reptile’s enclosure need?Pick the animal: enclosure size, the four temperatures, humidity, UVB, food and supplements, each figure with the body that published it.
• 🧪 Is your ammonia reading actually toxic?The same test result is harmless at one pH and lethal at another. Enter the reading, the pH and the temperature.
• 🐕 How old is my dog, really?Life stage first, human years second — because the ×7 rule was never real.
• 🐈 How old is my cat, really?The AAHA and AAFP life stages, and what changes at each one.
• 🍚 How much should they actually eat?The formula vets use, and how to turn it into cups off your own bag.
• 👋 Is my pet the right weight?Three questions, hands on the animal. The nine-point scale vets use.
• 💵 What does a pet actually cost?First year, every year, and the lifetime figure most owners get wrong by $50,000.
• 📏 What size does my dog take?Three measurements, and the sizes that follow from them.
• ⏳ How long has my dog or cat got?Not the average lifespan. The years ahead for an animal that has already reached its current age.
• 📅 What happens when in the first year?Every vaccine, worming, test and window of the first year, dated from the birthday, with the guideline behind each one.

How to get a useful answer out of one

• Weigh the animal if you can. A guess of ten pounds either way moves most of these results more than anything else you type.
• On the poison ones, assume they ate all of it. People almost always guess low.
• Keep the packet. Every poison calculator here ends with a line you can read straight down the phone, and the first thing a poison line asks for is the brand.
• None of these diagnose anything. They do arithmetic on published figures so that the conversation you have with a vet starts further along.
