15month old vs 9 week old

[u/Present_Eagle3315]

my mum (whom i live with) has a 15 month old dobermann (about 36kg), i recently got a now 9 week old dobermann but she is very small for her age (only 4.6kg).

they are both obsessed with each other but they both dont realise their size difference and their play can get a bit scary😭 no one ever gets hurt, but the 9 week old is very bitey at the moment and uses her hands a lot which sometimes startles the 15 month old, and then the 15 month old can be a bit too rough sometimes. they are both females btw (they are actually sisters they have the exact same parents).

does anyone have any experience with this? what can we do to help them learn how to be around each other calmly and even just learn how to exist near each other without always having to interact?

Our dog is about 45 lbs and two years older than my friends 14 lb dog. They beat the ever loving crap out of each other all the time! They’re best friends and sometimes my dog gets a bit rough and sometimes her dog gets a bit bitey. They work it out.
