Mars divests Whistle to Tractive — collar market state

“Empires don't sell off devices when the strategic value is rising. Mars's vertical-integration thesis just contracted — the empire that bought Whistle in 2016, AniCura in 2018, VCA in 2017 just let go of one of its data-feed legs. The empire is starting to look smaller from the inside than from the outside.”

Atom's last year — what the data told us, and what I missed

“I read the data for six months. The signal was there. I was watching the wrong metric. The metric a healthy dog tracks is not the same metric a sick dog tracks. Different dashboards for different stages.”

Mars Petcare — the food company that owns your dog's collar

“Pet wellness 'recommendations' that come from a company that also sells the prescribed food, runs the prescribing vet, and owns the analytics that 'detected' the need are not health advice. They're marketing channels. The conflict isn't subtle anymore.”

Whistle Health & GPS+ — the 'health' collar with no vital sign

“A collar that infers how your dog feels from how your dog moves is a clever accelerometer, not a medical device. Whistle calls scratching and licking 'health monitoring.' It's behavior monitoring with a wellness score on top — and the heart rate everyone actually wants still isn't on any consumer collar you can buy.”

Fi ships first units — Atom finally has a non-Mars tracker

“Two weeks on Fi. Battery life: 14 days actual, on a healthy active dog. That's 4-5× what Whistle 3 delivered. The LTE-M bet has paid off.”

Six months on the Whistle GPS Pet Tracker — the cellular realities

“Claimed 7-day battery. Real 3-4 days the moment GPS is doing the job you bought it for. The 'when it matters' number — dog out, located every few minutes — is closer to a single day. Divide the box claim by two for steady state, by seven for the emergency.”

Whistle's GPS Pet Tracker ships with cellular — and Mars Petcare buys Whistle the same month

“A pet-food company now owns the collar that tells me whether my dog is active enough. That isn't a theoretical conflict — it's the same firm saying 'feed more' and selling the food.”

FitBark — the pet activity-tracker market in 2015

“Two accelerometers on one dog for a week. They agree on the shape of every day and disagree on the size of it by a fifth — because they draw the line between 'resting' and 'active' in different places. The shape is the dog. The size is a setting.”

Tagg vs Whistle — cellular vs BLE pet-tracker philosophies

“Cellular tracker, $7.95 a month. BLE tracker, nothing a month. But the subscription isn't the real difference — the radio is. One keeps a cellular modem half-awake and dies in three days; the other sleeps until your dog walks past the house and lasts a week.”

Atom arrives — Whistle launches a dog fitness tracker

“Whistle is Fitbit for dogs. That's the easy comparison. The harder question is whether tracking activity actually tells you anything about a dog's health or whether it's just a number we like to look at.”
