The "rarest pet" depends on whether you mean in real life or a video game, but in real life, it's often a critically endangered animal like the Northern White Rhino (only two left) or Vaquita porpoise (fewer than 20), which are too endangered to be pets. In games, rarity varies, with titles like Huge Nightmare Corgi in Pets Go or special event pets in games like Grow a Garden or Adopt Me! being incredibly rare due to low drop rates or limited availability, sometimes only held by developers.
The Vaquita (Phocoena sinus), a small porpoise from the Gulf of California, is widely considered the world's rarest animal, with only around 10 individuals left, pushed to extinction by illegal gillnet fishing for other species like the totoaba. Other contenders for rarest include the Northern White Rhino (only two females remain) and the elusive Saola (Asian Unicorn), though population numbers for many extremely rare animals are uncertain.

The "million-dollar dog breed" most famously associated with record-breaking sales is the Tibetan Mastiff, with individual puppies selling for over $1.5 million and even nearing $2 million in China as status symbols, though regular prices are lower. More recently, a unique wolfdog hybrid, Cadabomb Okami (Caucasian Shepherd/Wolf), reportedly sold for $5.7 million in 2025 due to extreme rarity, but the Tibetan Mastiff remains the iconic symbol of luxury dog ownership, driven by its lion-like appearance and ancient lineage.
The #1 smartest dog breed, consistently ranked by experts like Dr. Stanley Coren, is the Border Collie, known for its exceptional ability to learn commands quickly (sometimes in under five repetitions) and obey them consistently, excelling in problem-solving and demanding mental stimulation. Other top contenders for intelligence often include the Poodle, German Shepherd, Golden Retriever, and Shetland Sheepdog, recognized for their trainability and eagerness to please.
There's no single "number 1" laziest dog, but the English Bulldog is consistently ranked at or near the top for its low energy, love of naps, and tendency to be a couch potato, followed closely by breeds like the Basset Hound, Great Dane, and Shih Tzu, all known for being relaxed companions. These breeds prefer lounging and short strolls over strenuous activity, making them ideal for laid-back owners.
What makes a good pet is a good pet steward.
