I think I found the info I was looking for.. lol I'll paste it just in case anyone else is curious or going through the same thing...
Bubba recently starting marking in the yard.. So according to this he's just hitting adolescence.. AND the second fear imprint period. Niiice.
"""Adolescence can appear in smaller dogs as early as five months. In larger breeds, it can start as late as nine or ten months. In giant breeds, adolescence doesn't take place until twelve to eighteen months. In general, the larger the dog, the longer it will take to physically mature. Some breeds can remain adolescents until they are two and a half, or three years old. Adolescence is expressed in male dogs by scent marking behavior. Scent marking behavior is stimulated by the release of testosterone into the dog's system. At this time, males may become macho. Male dogs may become less friendly and even somewhat aggressive to other male dogs. He may begin lifting his leg in the house. He may become very interested in girls, tend to roam, and certainly not interested in listening to you! Some males at this age become totally unruly. In females, adolescence is marked by the onset of the heat cycle, estrus. During this three week period, your bitch could become pregnant. So, keep her away from all male dogs. Bitches exhibit erratic behavior during estrus. Some get real moody and insecure. Others become quite bold or even aggressive.
Adolescence is a very difficult time for pet owners. They are surprised when their cute little puppy becomes a free and independent thinker. Adolescence is certainly a good time to start (or reinstitute) rigorous training. You must work hard NOW to mold the dog of your dreams.
Establish yourself as the leader of the pack. Be realistic about your expectations. You cannot expect young dogs to grow up overnight. Learn to appreciate your dog's adolescence for it is a truly wonderful time. At this time of their lives, dogs are very energetic and exuberant in their responses. They can be full of beans, but still, delightful playmates. You as the owner must learn to channel that energy and exuberance into learning, working, exercising, and playing games. It is not too late to train (or retrain) your dog to help him to become a long-lasting companion."""
"""The Second Fear Imprint Period is similar to the one that occurred during the socialization period, but, it is much less defined. It occurs as dogs enter adolescence and seems more common in males. It is often referred to as adolescent shyness. Your dog may suddenly become reluctant to approach something new or suddenly become afraid of something familiar. This behavior can be very frustrating to the owner and difficult to understand because its onset is so sudden and, seemingly, unprovoked. If you notice this behavior, it is important to avoid the two extremes in response: Don't force him to do or approach something frightening to him and don't coddle or baby him. To get through situations that make your dog fearful, be patient, kind, and understanding. Desensitize him to the object or situation by gradually introducing him to it and using food rewards and praise to entice him to confront the fearful object or situation. Do not coddle or reassure him in any way that will encourage his fearful behavior. Do not correct him either. Simply make light of it and encourage him give him food rewards as he begins to deal with his fear better. Make sure you lavishly praise his attempts! This phase will pass."""
