I have a 4pound yorkie who is 2yrs old, I also have a standard poodle that is a year and a half. Those two are the best of friends and play together all the time..They do get alittle wild sometimes...but I watch them and when things get alittle out of control I just put my yorkie on my lap to get his mind off of things...and things seem to settle down fine. My yorkie even takes his nap on top of my poodle. All as I can say is just keep an eye on them. I have never had any problems |
