Chloe...it depends.
No, in the fact that she can be left at home alone for 10 hours without any incident, when you get home all you have to do is let her out to pee and do a game of tug/fetch with her and she's good to go for the rest of the evening. If I were living in a country setting, had a submissive male dog, didn't have to worry about other family members interacting with her, and never had any visitors ever she would be the best, easiest dog.
As it is, whenever a guest comes over she has to be locked away, which makes her anxiety issues sky rocket. But if she's left loose with guests, they have to be very familiar with her and we have to watch every interaction they have like a hawk to avoid Chloe snapping. She doesn't get along well with female dogs and will aggress/redirect if she thinks her authority has been challenged/she gets frustrated. I have to be the one to groom her to keep everything as stress free as possible. If she goes to the vet, I have to be the one to restrain her (although she does FABULOUS, even if she is stressed out the wahzoo). She gets anxious during car rides. If she's crated or left alone in an unfamiliar environment she barks non stop. So, in those ways...she is not low maintenance.
Cynder and Gracie are the epitome of low maintenance dogs. They don't need walked. They don't need let out with a leash. They have a wash and wear coat. They sleep all day. They can be left alone all day long and, like Chloe, are satisfied with a quick romp outside, a quick play session inside, and then are good to go. They don't destroy anything. They don't have any anxieties. Riding in the car is second nature to them. They get along with other dogs. I could go on. Having these dogs is like...cakewalk. LOL Gracie does have allergies that she's currently on Temaril-P for, but she takes pills like a champ so that's okay.
Cooper is a little bit more high maintenance in that he has to be groomed, he can't be left loose or he'll pee on the floor, he is a submissive peer so you have to be careful how you approach him or he'll tinkle, he has mild separation anxiety, and he's dumb as a box of rocks. But he's still fairly low maintenance.
