Hi, so glad to see you again and congratulations on your new baby.
I never had any issues adding a new puppy to my pack. I had 3, all 3 years apart. Puppies have a different smell than adult dogs. Whenever I bought a new baby home my older ones were scared of it, they didn't know what it was lol.
With nippy puppy hanging off the older ones tail or whatever the puppy could latch on to, my girls stayed on high grounds (the sofa). It took about 2 months before the older ones would stay on the floor with crazy, nippy, zooming baby.
Always make Enzo first for everything, first to be patted when you come home and they greet you, first to have his food bowl put down, first to get the treat.
Make sure Enzo has a safe haven to get away from crazy baby. They will become BFF, it will just take a lil bit of time for Enzo to get use to the new crazy kid.
No walks for the puppy until it has had all vaccines, appox. 5 months old.
As Lovetodream has written, parvo can be bought into the home from the soles on people's shoes.
Puppies are so much fun, enjoy yours, they grow so fast .
And do let us know how they are coming along.
