Affidiamo il cane quando diventa adottabile.

Affidiamo is the 1st person plural present indicative of affidare.

Literally, affidare often means to entrust, to place in someone’s care, or to hand over responsibly. In the context of animals, it can mean something like:

• we place the dog
• we give the dog into someone’s care
• sometimes, depending on context, we rehome the dog or we let the dog be adopted out

So the exact English wording can vary, even though the Italian verb stays the same.

Because Italian usually drops subject pronouns when they are already clear from the verb ending.

Here, affidiamo ends in -iamo, which tells you the subject is we.

So:

• (Noi) affidiamo = we place / we entrust

Adding noi is possible, but it is usually only used for emphasis or contrast.

Italian uses articles much more often than English.

So il cane can mean:

• the dog — a specific dog already known from context
• sometimes a more general the dog in a procedural or general statement

English often leaves articles out in places where Italian does not. In Italian, cane by itself would usually sound incomplete here.

Because diventa means becomes, not is.

So the idea is:

• quando diventa adottabile = when it becomes adoptable

This suggests a change of status. The dog is not adoptable yet, and later reaches the point where it becomes adoptable.

If you said quando è adottabile, that would mean when it is adoptable, which focuses more on the state itself, not the transition into that state.

The subject of diventa is still il cane.

Italian does not need to repeat it the way English often does. So the structure is:

• Affidiamo il cane = We place the dog
• quando diventa adottabile = when the dog becomes adoptable

Italian simply leaves the subject understood from context.

It can often be understood as a general rule, habit, or policy.

So:

• Affidiamo il cane quando diventa adottabile can mean something like
  We place the dog when it becomes adoptable
  in the sense of that is what we do

Italian uses the present tense very naturally for procedures, rules, and regular actions.

Depending on context, it may also sound somewhat future-oriented, but without more context, the most natural reading is usually habitual/procedural.

Yes. That version would point more clearly to one future event.

Compare:

• Affidiamo il cane quando diventa adottabile
  = a general procedure, policy, or habitual action

• Affideremo il cane quando diventerà adottabile
  = we will place the dog when it becomes adoptable

So both are possible, but they do not sound exactly the same.

Adottabile is an adjective meaning adoptable.

It describes something or someone that can be adopted or is ready/eligible for adoption.

That is different from:

• adottato = adopted

So:

• adottabile = able to be adopted
• adottato = already adopted

Yes, it is completely normal.

The sentence is structured like this:

• Affidiamo il cane = main clause
• quando diventa adottabile = time clause

This is a very common pattern in Italian. English uses the same kind of structure:

• We place the dog when it becomes adoptable

You could also put the time clause first:

• Quando diventa adottabile, affidiamo il cane.

That is also correct, though the original order is very natural.

Because the clause with quando is closely connected to the main idea and naturally completes it.

In Italian, a comma is usually not needed before a time clause like this when it comes after the main clause:

• Affidiamo il cane quando diventa adottabile.

If the quando clause comes first, a comma is normally used:

• Quando diventa adottabile, affidiamo il cane.

So the punctuation here is standard.
