Reading this topic makes me want another sammy dog. I can't believe it's been a year and a half without a dog. I've been to the pound a few times and played with a few of the dogs, but none of them really connect.
That's the other nice thing about older dogs, they show their personalities, and what kind of dog that they are. While I hope that all the dogs that I have seen at the kennel make it to a forever home, I know that they aren't the right dog for me. (**I know, I know, I can't have a dog anyways, and it's a bunch of wishful thinking. But going to the pound just makes me feel better and I signed up to be a volunteer there**).
As for the dog smell. Kiani got baths often enough, at least once a month. She looked like the most miserable dog in the world. These sad eyes, her mouth closed, and would sit when I needed her to stand or stand when I wanted her to sit. On average, she smelled pretty good. But I would call her my mutt when she needed a bath and stunk. Which was usually after going to the dog park. And trust me, you might get used to the dog smell of the home when you're living in it, but outsiders might notice the smell of an animal in the house long before you do. Every pet home I've been in, I've been able to tell, and it's not a bad smell, just a "pet smell" if that makes any sense.
That's another thing, do you even know where your closest dog park is? Have you been there before? Met other dog owners? Almost any dog park I went to, there were occasions when people would stop in just to play with some of the dogs or watch them play. It was a BIG deal to my dog to go there. She even tried to jump out the car window when I was in the parking lot pulling up. She knew when we were on our way to one.
Walks are all good and such, but they need some actual play time and social time. I've been to good parks and bad parks. We did live in an apartment all of her life, so there was never a backyard for her, but I'd think she'd just lay there and be bored. She was never amused by toys or dog treats or any of the usual dog stuff. Even at the dog park, she wouldn't chase a ball thrown or tug of war, she'd follow the other dogs that were running, just to run. She was a puller/working dog. Her joy came from that, so I stuck her leash on my
scooter and off she went. At one point we only lived about 6 blocks from a dog park, so she'd pull me there and then usually trot in front of me on the way home. You'll have to work with your dog's personality to see what stimulates them, makes them happy, tired, and exhausted. I mean to me, it seemed like a lazy way out. I just stood on a scooter trying to not get myself killed. She enjoyed it much more than going for a walk, and constantly tugging on the leash trying to reach for the new smell on the ground, or being annoyed when I used a halti on her.
When we'd go on vacation, usually Disney, she'd come with us. She never minded being in the kennels, and knew we'd be back in a short while to get her and play with her some more (this was when Disney owned them, and you had to walk and feed your own pet). We would also stay at the campgrounds so we could keep her with us at night. If we went any place else, it was always some place we could go and bring her with us.
This vacation coming up isn't going to be your last vacation for the next 15 years. Kennels and boarding places are expensive, even having a personal pet sitter is expensive. You say the breeder will keep the pup a bit longer to cover you this time, but next time, it's all you.
