Hi all..
.Well I think if you are going to get the two..get them together as pups..training shouldn't be any more difficult than having one really...you will just need two pairs of eyes..if you see what I mean.!!
Our first Yorkie..many moons ago was on his own for 2 years..then we decided to get another one. He didn't take too kindly to the new pup at first..I reckon he felt like he was being pushed out...so had to give our elder yorkie lots of special attention too. Over the years we have always kept 2 yorkies...when we have lost one..we have gone out and found another pup. to keep our other dog happy.
At the moment we only have the one...he's 10 now..and just lost his soulmate in July but he is very independent little soul..so we are probably just staying with him for now.
Go and get the 2 I would say...it will help for when you are out at work.
