"I had a pooch like this" makes no sense

"I had a pooch"...

(though anthromorphizing, 'cutesy' word that animals should not be thought of as, because they're animals first. Animal, species, breed, THEN 'name', but people always think of especially 'pet animals' as 'little humans' and every single hag that does this thinks they are being completely unique and original in doing so)..

...might make some kind of sense, but I had a pooch LIKE THIS doesn't.

So, he's holding up just the leash and says 'pooch like this'. Like what? What are the options here? He doesn't KNOW what kind of dog it was, so are we to assume he means a dog that is:

- invisible and weigthless?
- exact clone of a leash?
- already dead, so he's pointing out to the dog's spirit/ghost we can't see?
- completely bodiless?
- the 'joke dog' Alan bought from Las Vegas in one of the 'Two and Half Men' episodes, that consists of a 'stiff, but wobbly leash you can move to make it look like you are walking an invisible dog' (and doing even that wrong by letting it in front of you)

What kind of sense does it make for the cop to say 'like THIS'?

Sure, he had some kind of dog as a kid that he liked to call 'pooch', thus never understanding the dog psychology, so the dog would probably HAVE been better off dead, but 'like this'??

What does 'this' refer to, exactly? To the mangled carcass miles away in the bushes where no one can see it? To little pieces of a dog body?

Did the cop follow them for long enough to actually have seen the dog, and why refer to the dog as 'this' instead of 'that', since the DOG IS NOT HERE WITH US (from his perspective)?

There are moments in movies that keep bothering me more and more until I can't take it anymore, and this is one of them. 'Pooch like this'? No.

'A dog I treated badly because I did not understand rules, boundaries, limitations - or exercize, discipline, affection. I just treated it as a 'pooch' instead of animal-dog, so I never fulfilled its psychological needs'? Yes.

So what the heck is going on here? Is the cop on LSD and is seeing floating dogs all over the place?

Is the cop so emotional about it, he actually sees a dog when holding the leash?

Is there a photo of the dog on the leash?

Is..

You get the idea.

This scene makes NO sense whatsoever!

I hate when even the most classic, great movies have to have a scene that makes zero sense. Sigh.
