This is not news. Many giant domesticated dog breeds can double and even triple in size in the first 6 months.
From birth to about six months, giant breeds grow explosively.
• Great Dane pups can go from a tiny 1–2 lb newborn to over 70–90 lbs by 6 months.
• English Mastiffs can reach 100 lbs in that same time frame.
• Irish Wolfhounds often gain 10 lbs per month for their first half-year.
• Giant Alaskan Malamutes follow suit, though they may plateau a little earlier.
And many American Dirus dogs go from 1 lbs 6 oz at birth to 90 lbs at 6 months.
Plus… remember folks… these are GMO gray wolves with at least one domesticated dog gene - not dire wolves.
Dire Wolf Project, Inc. remains the only breeding project in the world dedicated to bringing back the exact bone and body structure of the extinct, prehistoric dire wolf in a loving family companion dog using only domesticated dog breeds.

Just six months ago, Colossal Biosciences unveiled a stunning breakthrough in de-extinction science by introducing three genetically revived wolf pups: Romulus, Remus, and Khaleesi. Born from advanced genetic engineering inspired by ancient DNA, these pups were hailed as the next step toward bringing back the long-lost Ice Age predators that once roamed prehistoric landscapes. Fast forward to today, and these creatures are making headlines again, not for their origins, but for their incredible rate of growth. Romulus and Remus, the two male wolves, have already crossed the 90-pound mark, making them a staggering 20 percent larger than the average modern grey wolf. Meanwhile, Khaleesi, though younger and slightly smaller, is still defying expectations at 15 percent larger than scientists originally predicted. What’s most astonishing is that this explosive growth is not entirely understood. Scientists speculate that the ancient genetic code preserved within these animals may be activating growth traits once common in their Ice Age ancestors. These enhanced wolves may represent a glimpse into a forgotten past where apex predators ruled vast, frozen terrains with unmatched strength and endurance. These breakthroughs aren’t just about reviving extinct animals. They offer insights into how ancient ecosystems functioned and how modern technology might one day help rebalance our own fragile environment. While ethical and ecological debates continue, one thing is clear: Romulus, Remus, and Khaleesi are rewriting what we thought possible in paleogenetics. Fun Fact: The DNA used to engineer these pups was partially reconstructed from preserved tissue samples of the now-extinct Pleistocene wolf, an ancestor of today’s grey wolf.
