Great news about your puppy.
I babysat my yorkie grandson while the family vacationed in Hawaii. Every time I sat down he (Studley)jumped into my lap and took a nap. Luckily, my lap is big enough to share space for Studley and our Bishon Frisee, Gizmo. Our golden retriever, Bailey, was content to sit and lay beside me as long as I petted him and gave him equal attention. He would be quite a large “lap dog”.
I have a friend who has three weimaraners, and as soon as he sits down in his recliner, and puts the foot rest out, all three of them become 'lap dogs'! Each has it's own 'space' on his legs, thighs and tummy.
Can you imagine THREE of these guys as 'lap dogs' at the same time? LOL!
