Woody and Winnie will become best buddies over time and very protective of one another. Just make sure when Winnie reaches full size she doesn't start bossing Woody around as that might build some tension between them. Young dogs often take the tolerance of an older dog while they are small and developing, especially during play and confuse the message with such tolerance being a green light for the younger dog to challenge the older dogs pack leader or dominance status. It doesn't happen often, but if you notice their "play" getting rough as Winnie grows and she seems to be more serious, its best you intervene and just say NO.
Woody is thinking "This kid is learning" and he is putting up with a little more and more as Winnie grows. Usually, Woody will let her know when she is going too far. It might even take a nip or two for Winnie to get the message as she gets bigger. If you sense the tone getting nastier as Winnie gets bigger, just don't let her push it to the point that Woody will feel the need to defend his status. The vast majority of the time, a snarl or nip is all it takes to keep everything on a level playing field. But if you notice this snarl or nip is happening more often or is turning into several snarls and nips, its best you stop it.
One day, Winnie will realize she no longer has a physical disadvantage in size and challenge him more and more. Age, gender and even physical size don't determine who is the pack leader. Its all about attitude and the willing to back it up. These issues are more likely to surface when there are multiple dogs. Just monitor their play and interaction and as Winnie grows, she is likely to keep grabbing more and more authority in their relationship. It sounds like she doesn't back down easily now, which is why I mention this issue. One day, he is going to nip her or do something when he is tired of dealing with her "pushiness", which is all part of a dogs growth. Woody will determine just how far he will let her go and as long as she respects the limit he sits, everyone will get along great. But if she keeps insisting on pushing the envelope, he will likely make his role very clear to her.
Chances are, they will be best buddies and there is no doubt, Winnie will help keep Woody younger. You did the right thing by adopting her. Its better for you, Woody and Winnie, all for different reasons. No doubt she is a cutie.
Try and get her to go potty ASAP at 3am when she get you up and then right back into the house and bed. Keep telling her "Go Potty" or whatever you might call it and then really praise her when she does go outside as you want. Do this positive reinforecement Each time and she will catch on very quickly. It will become a game she will like to play and you can even develop it to get her to go on command, which is handy when you have to leave, etc. Or for a urine sample at the vet during visits, etc. She will catch on quickly. We always give our girls a piece of a "Nudge", which is a meat type dog treat. I tear them into 3 or 4 pieces, so each one is like one bite. No need for a full sized treat. One bite size piece will get the message across.
If you let her play after the 3am trips outside, she will fully wake up and so will you. Plus, right now its not to bad but as she grows up and her body develops, she should be able to go longer periods of time before going outside to have to TCB. Of course an upset stomach or such can always change things temporarily, but overall, she should get to the point where 6 to 8 hours or more of being in the house shouldn't be a problem.
Never punish accidents in the house as dogs so live in the moment, they often don't understand what they are being punished for unless you catch them in the act. Even then, a stern "NO" and take her outside and then the praise when she does go and soon accidents will be a things of the past. Just like people, they respond to kindness and love much better than negative responses.
What a great looking canine family you have. I bet you will notice Woody seems more active and even acts "younger" over the next year. Bringing WINNIE into your family is great for her, you and Woody. Dogs are such great family members. I am glad you adopted Winnie and thank you for sharing Winnie and Woody with us here on GTT. I am sure many enjoy this just as much as Mrs. Bear and I do..............
