I am sure Daisy will put the pup in her place but from what I have found out with mixing my two pups with other dogs is that an older dog will 99.9% of the time not hurt a pup, so I wouldn't worry.
Yesterday, my mums golden retriever who is MASSIVE
had a go at Herbie (13 weeks old). Herbie couldn't stop crying
, even about a minute after he was attacked he kept yelping out. I had to cuddle him for ages. I checked him over and he was fine, not a mark on him (just a bit of slobber), in fact jasper left him for about 10 mins then came over to lick his face.
Jasper could have really hurt Herbs if he wanted to, he was just putting him in his place. Like my mum said - sometimes, I tell my children off and they cry - I guess this is what Jasper did to Herbie.
Sounds like Daisy was telling the other dog "go away it's my stick", and quite rightly too
I wouldn't let this incident spoil your excitment of getting your new pup
