pups adapt to routine pretty quickly, i have been through the puppy stages with all of mine with the exception of 1 lurcher, i have had no problems, the sooner you teach your puppy the routine the better, i have a puppy here at the moment which is fitting into my routine very well, as long as they have a nice dry weatherproof kennel and bed to cosy into and plenty of food and water then they are happy, i have the company of other dogs for my pup but she is left herself for small amounts of time when i'm home just to get her used to it, it's not hard to teach 1 pup a routine or 2
