I'm sure they will get on. I had an eight week puppy which due to hospital changed dates had to go into kennels for 2 days with my other 2 dogs within a week of coming home. The kennels put a camera in the pen they were all in and one big basket. The owner was amazed at how they slept together and let little one eat there food even though she was fed by the kennel staff with puppy food. This bond last forever..
