If you are a first time dog owner and not familiar with training dogs I would STRONGLY advise not getting two puppies at the same time. If you are interested in a second dog, please give your new puppy your full attention for a year first then consider either a new puppy or a second adult.
You can read lots of professional opinoins on this question at the link below. Not ONE recommends two puppies at once unless you are a professional trainer. You can have very serious behaviour problems and if you aren't an experienced trainer, managing two can be overwhelming.
With all due respect to those who have done this -- whose dogs I haven;t met so this is no comment on any individual here!
-- I have also found that many folks who find they personally had no problems with their two puppies and recommend it to others, actually have two adult dogs that are not very well trained and under control and are not very pleasant for other people to be around, but the owners don't see this. This is not always the case of course!!
but this is probably the case more times than not. This isn't the fault of owners, it is just that inexperienced owners can find it challenging enough to give full attention to and train one puppy; two means neither are very well trained, they establsih ways of ignoring the people around them as they typically bond very closely, and as they often get away with murder as puppies, they continue to do so as adults.
I was an experienced dog person coming into getting my first and found one puppy incredibly demanding -- and I work from home where I can give almost full time care to a dog. Getting Leo when Jaspar was 10 months was STILL too early to have had two and Jaspar's training suffered as a consequence.
That is why many breeders will not hiome two puppies together, and why most recommend getting a second dog at 12-18 months, 18 being better than 12. I wished I had listened to that advice myself a little better! :lol:
