WARNING: They are called “Retrievers” for a reason!!! THEY PUT EVERYTHING IN THEIR MOUTH!!
In my experience, puppies often have a “witching hour” once or twice a day. Sometimes this is because they’ve been cooped up too long… BUT sometimes they’ve been OUT too long and really, really need a nap! Sound familiar? Anyone met a toddler before? So if you’ve exhausted all the advice in the above articles, it’s ok to put puppy in his crate with a chew toy and walk away!
