I have 6, but to make thing simpler we never get another dog until all the dogs we alreadu have are at the very LEAST a year old, but we prefer to wait untill all other dogs are fully trained so that we can focus on one dog at a time. otherwise all we need is more room on the counter for the dogs dishes when we make theire brecky(they are fed raw) its not more expensive because our butcher gives us all we want for free, well to ALL raw feeders, just go in the back and take all ya want! otherwise I want more!!
