The use of 'Mops' (dough/money) for 'Geld' (money) is purely colloquial and is considered somewhat outdated. Today, you hear it only rarely, mostly from older speakers or in a joking tone.
Ohne Mops ist hier nichts los, sagte mein Opa immer.
Without dough, nothing's happening here, my grandpa always used to say.
You can easily recognize the meaning 'Geld' (money) from the context. If it is about paying, buying, or finances, it does not mean the dog.
Das neue Fahrrad kostet ganz schön viel Mops.
That new bike costs quite a lot of dough.
Typical phrases are 'keinen Mops haben' (to have no money) or 'ordentlich Mops kosten' (to be very expensive).
Ich kann nicht mit ins Kino kommen, ich habe leider keinen Mops mehr.
I can't come to the movies; unfortunately, I don't have any dough left.
money
'das Geld' and 'der Mops' can both mean money, but they are used very differently. 'Geld' is the normal word and always fits when talking about paying, saving, or wealth. In this meaning, 'Mops' is colloquial and rather outdated. Many people today first understand the word as a dog breed. For learners, 'Geld' is therefore almost always the safe choice. 'Mops' is at most suitable in old, joking, or very casual texts.

Mein Großvater sagte manchmal scherzhaft, er habe keinen Mops mehr in der Tasche.
My grandfather sometimes jokingly said he had no dough left in his pocket.
Wir brauchen noch Geld für die Miete und den Einkauf.
We still need money for the rent and the groceries.
