btw, i am THE official "worrywart" of dogtrickacademy,
so do take stuff i say with a grain of salt,
cuz i freely admit, i AM a bit of a dog-health worrywart.
but, there's some ppl who think you do not want a puppy under 18 months old
standing on his hind legs.
(nor only on his 2 front legs, either)
Or only super briefly, not done repetitively anyway.
Some say not til 24 months old, some say it's okay at 12 months old.
The reason for this caution is,
that a dogs bones aren't 'set' yet, that the puppy skeleton is still hardening up til pup is 18 to 24 mos old, and you don't want to stress the joints til they are fully hardened, so that dog has better chance of having an
old age with less chance of joint damage bothering him.
Others may disagree, the internet if full of conflicting info on this, but i always err on the side of safety when it comes to my dog's health
.
Others say puppies under 18 to 24 months old,
should not be
doing much
long-distance running/ jogging/trotting,
nor jumping from high places, or excessive amounts of repetitive movements which could stress their still-soft joints and bones.
but it is also easy enough to find dog owners who say "nah, it's all good, go for it, my puppy did it and his little puppy hips are
just fine"
so each dog owner has to make up their own mind about their puppies skeleton safety.
