τί ὁρῶμεν [ὁράομεν] ἐν τῇ εἰκόνι;
ἄνδρα τινά τε
κύνα τινά τε καὶ
λύκον.
καὶ δένδρον ὁρῶμεν. ὁ λύκος ἐστι ὑπὸ τῷ δένδρῳ, ἀλλὰ οὐχ ἡσυχάζει. μέγας ἐστίν ὁ λύκος, καὶ ἄγριος (wild, savage). ὁ δὲ ἀνὴρ λέγει· ἴθι δὴ, ὦ κύον, δίωκε, ὅρμα [ὅρμαε] ἐπὶ τὸν λύκον, τὸν κατάρατον. (remember chapter 2 when Dikaiopolis calls his lazy slave "you rascal" ὦ κατάρατε.)
 
Philip has obviously found τὸν κύνα, τὸν Ἄργον but not only.
We ὁρῶμεν [ὁρά-ομεν] =  βλέπομεν 
τὸν Φίλιππον τε καὶ τὸν κύνα καὶ λύκον (a wolf) ὑπὸ δένδρῳ (under a tree).
In lesson 5a ὁ πάππος λαμβάνει τὸ βάκτρον / τὴν βακτηρίαν but now it seems that
ὁ Φίλιππος ἔχει τὸ βάκτρον/τὴν βακτηρίαν.
Though in the text he will use a μάχαιρα  (knife) to strike the wolf. Little artistic licence I suppose.
 νῦν δὲ  (but now) οὐ λέγει:
 ἴθι δή, ὦ Ἄργε, διώκε τὸν λαγών but:
 ἴθι δή, ὦ κύον, ἔμπιπτε τῷ λύκῳ .
Go on, attack ἔμπιπτε  from πίπτειν to fall + ἐν = in, on.
And so the dog ὁρμᾶ ἐπὶ αὐτόν.
ὁρμάω sounds difficult, but since we talk a lot about "hormones" that stimulate cells and tissues, hurriedly carried by blood or sap through organisms, we should have no trouble in remembering the origin of their name: ancient Greek, ὁρμῶσιν [ὁρμά-ουσιν] they rush.

We've seen:
 
σκαιός, σκαιά, σκαιόν: clumsy
πταίω: I stumble
καταβάλλω: I drop
θραύω: I break
πίπτω: I fall
ὁ Ξανθίας σκαιός ἐστιν. πταίει οὖν καὶ καταβάλλει τὸν λίθον ἀλλὰ οὐ πίπτει αὐτός (doesn't fall himself). ὁ δὲ λίθος πίπτει, πίπτει πρὸς τὸν τοῦ Δικαιοπόλιδος πόδα.
καὶ ἡ Μέλιττα σκαιά ἐστιν. πταίει καὶ αὐτὴ (she also stumbles)· καταβάλλει τὴν ὑδρίαν καὶ θραύει αὐτήν. ἡ γὰρ ὑδρία πίπτει πρὸς τὴν γῆν καὶ .... οἴμοι.
ὁ κύων ἐμπίπτει τῷ λύκῳ is more or less the same as ὁρμᾷ [ὁρμάει] ἐπὶ τὸν λύκον.
