We have a cavalier cross ****er spaniel and a cavoodle. Had both from pups and when DS came home one was 2 and one was 4. Dogs sleep outside and come on for varying periods during day.

We sat on couch with DS and let dogs sniff on a regular basis, in time they licked his feet (would not let them near face and hands.)

As he got bigger we would have him on floor on a blanket and dogs would come and sniff him.

Since he has been moving him and dogs are all over each other and get alone great.

We did plan on DH taking home a blanket or singlet from hospital for dogs to sniff and get used to but never got there
