While a dog run is a great place to keep your dog safe and sound a dog that has been living outside, running freely in the backyard or living inside theneeds some time to adjust to living in a dog run. The change for a dog that has been roaming freely around the yard and that now finds itself in a dog run can be difficult for it to understand. It will find its new home strange and different. It might even feel like you are angry at it and therefore punishing it.
Every dog is different and some handle change better than others but pretty much allare like humans in the way that they become accustomed to certain things and when those things aren't there anymore it is difficult for them to understand. This is especially true for older that have grown used to certain routines and have developed certain habits and understandings of the way things normally are. Then if their whole world gets turned topsy turvy this can have a very strong impact on them and if the situation is not handled carefully the impact could be negative.
Like with any aspect of dog care and training,need time and preparation and guidance to help them adjust to things and learn to adapt to new things. Whenever you are considering putting your dog in a dog run make sure to look at its present situation and plan out how you are going to help your canine friend adjust to its new way of life.
