I've seen this happen. The best example of this would be a friend who got a dog soon after moving in with his girlfriend. They got the dog at a time in their life when it didn't make sense to have that dog. They selected a dog that needed more space to roam than their 2 bedroom apartment. The dog was poorly behaved because it was too big of a dog for an apartment. They eventually moved to a single family house with more space for that dog, then eventually married and had children.
They did such a poor job with dog raising that their child raising skills are debatable.
The wild thing about this story is that it was an example of an established couple owning a dog. Single women might even be less equipped to handle dog ownership than a woman part of an established LTR.
In my personal opinion (haha always use this statement when talking about dogs) , I don't believe room is an issue providing the dog has a decent owner.
Training, suitable play and activities for the breed, consistency and dedication are more important.
A small home space completly aduquite as long as the dogs needs are properly furfiled.
Dog owners tend to give every excuse and external factor under the sun to explain why their dog is so messed up. Very few take accountability.
What boils my blood is the purely positive wack jobs. It's almost cult like , which comes from this fur baby culture.
As a trainer, my training style is massively based on positive reinforcement, shaping and building engagement (I probably train and work on these things and hour a day with my dog) . It creates a beautiful relationship.
I don't often use corrections or aversive methods.
BUT I have and WILL.
To me it's important to have a vast tool box available to reach into to solve problems.
It's become a big thing in the dog world to be "purely positive" never do anything the dog may perceive as a negative.
The reality dogs are dying because of these people.
They would rather put the dog down ot re-home if they can't fix problem with a treat, then proclaim they did everything they could but the dog couldn't be saved (due to some bull**** external factor/excuse).
