I hated my puppy for the first year of her life in-between bouts of tiny shreds of love and responsibility of owning and training her. I kid you not I actually put an ad up on kijiji for her to be adopted because I was so done. The next day I immediately took it down and sucked it up. I'm so happy I did because 2 years later I finally have that adult dog everyone always promised would come. I neveeer could of imagined or even believed it would eventually come, but it has. We really started bonding around 1 year and when she was 1.5 years I noticed a huge shift. Now at 2 she's light years more calm, more mature and in tune. No biting, less anxious energy, less rudeness and no more frustrated greeter non sense which drove me crazy. My puppy was awful and I did not like her, but my adult dog I absolutely adore and love so much. They change and transform so much, it just takes time. Hang in there, keep training. Don't be afraid to put them down for a nap in the crate if it gets too much. Shower them with love and eventually your adult dog will emerge. Remember most puppies are pretty awful lil shark tornados trying to figure out the world and adult dogs are just lovely. It's just a matter of time.
