Acogemos al animal a condición de que mejore la convivencia.

Acogemos is the first-person plural present indicative of acoger.

Here it can mean things like:

• we take in
• we welcome
• we accept
• we give shelter to

The exact English choice depends on context. With animal, it often suggests taking the animal in rather than just greeting it.

Because Spanish often uses the personal a before a specific animate direct object.

So:

• acogemos al animal = we take in the animal

Here, a + el contracts to al.

This is very common with people, and it can also be used with animals when they are specific or individualized.

Compare:

• Veo al perro = I see the dog
• Veo el coche = I see the car

Not always, but it is very common when the animal is:

• specific
• known
• treated as an individual

So al animal sounds natural if we are talking about a particular animal.

If the animal were more generic or less individualized, Spanish may omit the a more easily, depending on context.

It is a fixed expression meaning:

• on condition that
• provided that
• as long as

It introduces a requirement that must be met.

So the structure is:

• a condición de que + subjunctive

This is a fairly formal expression.

Because de is part of the fixed construction.

The noun condición combines with de que in this expression:

• a condición de que...

You should learn it as one chunk, not word by word.

Other Spanish expressions work the same way: a certain noun or phrase naturally requires a specific preposition.

Because a condición de que normally requires the subjunctive.

The subjunctive is used here because the improvement is:

• not presented as a fact
• a condition
• something expected or required

So:

• mejore = present subjunctive of mejorar

If you used mejora instead, it would sound wrong in this structure.

Mejore is the present subjunctive form of mejorar.

It can correspond to several subjects:

• yo mejore
• él/ella/usted mejore

In this sentence, the subject is not stated explicitly, which is normal in Spanish.

Spanish often omits subject pronouns, so the subject has to be understood from context.

In this sentence, the most likely reading is that the understood subject is the animal, and la convivencia is the object:

• provided that it improves coexistence / living together

That said, without more context, Spanish can sometimes allow a little ambiguity because word order is flexible. But the intended meaning is usually clear from the situation.

Convivencia is a very common Spanish word, but it does not always have one perfect English equivalent.

Depending on context, it can mean:

• coexistence
• living together
• day-to-day relations
• household harmony
• the way people or animals get along in a shared space

In a sentence like this, it often refers to the quality of life or harmony in a home, community, or shared environment.

Yes, it sounds fairly formal or administrative.

Especially these parts make it sound more formal:

• acogemos
• a condición de que
• la convivencia

It could fit contexts like:

• animal shelters
• adoption rules
• housing policies
• official notices

In more everyday speech, a speaker might choose a simpler expression, but this sentence is perfectly natural.

Because the present tense in Spanish can express:

• a general policy
• a standing rule
• a current decision

So Acogemos al animal... can mean something like:

• We take in the animal, provided that...
• We are willing to take in the animal, as long as...

This does not have to mean the action is happening right this second. It can describe a rule or condition that applies now.

Yes. Spanish has other ways to express a condition, for example:

• siempre que
• con tal de que
• si

But they are not always identical in tone.

• a condición de que is more formal and explicit
• siempre que often means as long as
• con tal de que can sound a little more like provided that

All of them are commonly followed by the subjunctive when they express a condition that is not yet fulfilled.
