I can't get my head round the logistics, and as a suitable puppy will soon be available, I need to figure this out.
Older dog is very reliable, well trained and will welcome new addition. He sleeps on his (custom made by me) bed in the kitchen at night but goes wherever he wants during the day. He is fully innoculated and wormed this week. Unlikely to be bringing around any nasties on paws etc.
To what extent do I keep the new puppy isolated until her injections are complete and she is fully wormed?
Will older dog be bothered if puppy spends a lot of time in crate (he wasn't crate trained himself, but he was very biddable and easily trained).
How much should I let them mix?
And any other hints you can think of.
