Our 14 year old dalmatian was always a house dog...she liked it outside but when she was inside, she liked that, too. Even before we got Boomer, she got to where she would be almost nervous in the house.....always wanting to go outside. Now she just wants outside all of the time....we have to make her come inside usually. Then, even when she wants to come inside, she is a nervous nelly and wants outside again within about 30 minutes or so...She doesn't have to deal with Boomer as we keep them pretty much separated by a doggie gate when they are in the house. I have heard other people tell me their older dogs got to where they preferred to be out of doors, too.....has anyone else experienced this? In all honesty, she is probably getting more stimulation outside with the birds, squirrels, and various other things to look at and listen to. Just wondering if this was half way normal...she is pretty healthy otherwise.....just a little weak in her back legs if she stands for a long time.
