"Vidíte mého psa?"

Translation: Can you see my dog?

[Christine_nl]

To me this sounds like "vidite me hopsa?"

[va-diim]

So the noun "dog" is treated the same as a masculine person in Czech noun cases?

[Alexandros_N]

In every day use what is more common or better to say? Vidite meho psa or vidite moje pes?

[ion1122]

The form "moje" would be correct with a neuter noun in the accusative singular, but "pes" is masculine, so must use "mého" in the accusative singular.

[Jamie08MD]

It's definitely the first option. The second one is not grammatically correct. The latter would work in plural (if you changed it a bit). If you had more dogs, you could ask: "Vidíte moje psy?"
