[ a non-exhaustive list of headcanons surrounding pups~ additions may be edited in or added with reblogs ]
A pupās dynamic is known earlyāsometimes from utero, but definitely from birth. There may be some confusion between alpha and beta boys, or beta and omega girls, but scent usually clears that up.
Pups, especially those from multi-births, are born a little smaller than IRL babies. They grow fast, thoughāthough said growth can make them very fussy :( Their parent or packmates purring against them eases the pain, though, soothing them.
They have a hard time generating and retaining body heat for the first three months, which means they need lots of cuddles.
Pupās noses are especially strong, and thus are more keenly aware of even subtle shifts in scents. Theyāre very wary around new scents. They easily become overstimulated by smells. Sometimes a particularly strong scent will make them sneeze.
Play fighting is common, especially among baby alphas. It can get a little too rough sometimes, though.
Pups often tend to explore things with their mouths, leading to a lot of biting even outside of teething. While this is good for building jaw strength, it often leads to a lot of biting things they arenāt supposed to.
Pups nibble on each other and their older packmates to show affection. Unfortunately, theyāre not always good at judging force, or teeth sharpness.
I saw a post on twitter about alpha pups being clingy towards their dams (particularly if theyāre an omega), and I love it. They growl at āintrudersāāwhich can include their other parent / packmates or strangers. They get bad separation anxiety, which can make the first day of preschool / kindergarten super tough š„ŗ
Conversely, (inspired by the same tweet as above) omega pups may cling to a specific parent, but also tend to just be clingy / cuddly in general. All they want to do is snuggle!
Beta pups are slightly more independentāthough some can be clingy or cuddly!ābut are often prone to wanting to wander around / explore their new surroundings as a result.
Nap time is taken in puppy piles / a communal nest. Pups will bring a blanket and/or pillow and/or stuffed toy from home to use in the nest. In sleep they all end up curling together / on top of each other; the room filled with soft, content purrs before they peter off into true sleep.
Recess can be chaotic, especially with puppies who like to tussle. Sometimes older students will volunteer to help monitor and make sure no one gets hurt.
Presentation happens around 12 to 15. Delayed presentations arenāt unheard of, especially in unsafe environments. The first fertile cycle generally happens between 17 and 19, though again, delays arenāt uncommon.
Presentations being hormones and instincts to the fore, and are very tumultuous for everyone. A presenting pup will often latch onto an older pack member during this time, and become extremely clingy.
Puberty is also when abilities develop. Sometimes alphas will slip into command on accident, when frustrated or mad. Omegas will find themselves using suggestion when sleepy or upset. Betaās scent slides all over the place. They may unconsciously mimic their packmates, friends, or crushes.
Scents also fluctuate just in general, growing stronger and losing the milky edge of early puphood. Some days they can be oppressively strong, causing pups to burn through scent patches.
Some pups get particularly protective and/or fussy over their nests, not letting anyoneāeven younger packmatesāin.
All three dynamics also grow their adult fangs around this time. Iām unsure if these fangs replace their baby fangs, or if they develop a second set which can be extended.
And, of course, pubertyāso everyone is becoming aware of the other dynamics & genders, learning their preferences. Pups will often begin their first attempts at courting.
