After living with one dog for some time you've decided to introduce a second into the family.
When you have chosen the dog, introduced him to your current pet and offered him a place in your home you will need to deal with the logistical side of bringing him into your family. This experience will be upsetting for everybody so must be approached and carried out in a positive way.
The 1st and most important thing is that your existing dog should not be mistreated or in jeopardy in any fashion. The dogs should have already met before a home is offered. No stress should be obvious and the 1st meeting should be on neutral ground. The dogs should be noted meticulously and their body language monitored. Positive interaction is important between two dogs that are going to live together.
The best thing to do is take them both for a stroll before bringing them into the home together. The home should have already been prepared by the removal of any resources that would cause conflict. Food and toys should be removed from all areas at first. Depending on how well the dogs get on toys can be reintroduced very swiftly and quietly. It is better to have a massive choice of toys than one; a single toy can be accepted as very precious to a dog that's inclined to resource guard.
Research and preparation is how to choose a dog which will successfully become your second family pet. Observation and further research will allow you to manage a positive settling in period.
It is very important to consider your own behaviour towards the dogs. Remember you are also considered a resource. It is going to be natural to stress about your current pet but don't leave either dog out of interactions. Some new dogs benefit from being left alone to settle and join in quietly, others wish to interact with you. To prevent stress developing it is important that you treat both dogs, when they ask for attention, in the same way.
