Anche se il cane è randagio, è adottabile.

Anche se is a conjunction meaning even if, even though, or although. It introduces a contrast:

• Anche se il cane è randagio = despite the fact that the dog is stray
• è adottabile = it is adoptable

So grammatically, anche se sets up a concessive clause: something is true, but it does not change the main point.

A useful note: anche se often takes the indicative in Italian, especially when talking about something presented as real or factual, as in this sentence.

In Italian, singular countable nouns usually need an article much more often than in English.

So Italian says:

• il cane = the dog

Even when English might sometimes be more flexible, Italian generally prefers an article with a noun like cane. Here, il cane refers to a specific dog or to the dog being discussed.

Because there are really two clauses here, and each one needs its own verb:

• il cane è randagio
• è adottabile

In English, we also repeat the verb:

• Even if the dog is stray, it is adoptable.

Italian can leave out the subject pronoun, but it usually does not leave out the finite verb. So the second è is necessary.

Italian often drops subject pronouns when they are clear from context. This is called being a pro-drop language.

So:

• Anche se il cane è randagio, è adottabile.

naturally means:

• Even if the dog is stray, it is adoptable.

The subject of the second è is understood to be il cane.

You could repeat il cane, but it would sound more repetitive:

• Anche se il cane è randagio, il cane è adottabile.

And using a subject pronoun like esso would sound unnatural in normal conversation.

Randagio is an adjective here. It describes il cane.

Because cane is masculine singular, the adjective is also masculine singular:

• il cane randagio

Other forms would be:

• la cagna randagia or la bestiola randagia = feminine singular
• i cani randagi = masculine plural
• le bestiole randagie = feminine plural

In this sentence, randagio means stray.

In Italian, adjectives often come after the noun, especially when they are describing a factual quality or category.

So:

• cane randagio = stray dog

This is the normal order. Putting many adjectives before the noun is either impossible, unusual, or changes the tone/meaning. With randagio, the post-noun position is the standard one.

Adottabile is an adjective meaning adoptable or able to be adopted.

It comes from the verb adottare = to adopt, plus the adjective ending -abile, which often means capable of being ....

Examples of the same pattern:

• lavare → lavabile = washable
• mangiare → mangiabile = edible
• adottare → adottabile = adoptable

So è adottabile means is adoptable.

This is an important difference:

• adottabile = adoptable → can be adopted
• adottato = adopted → has already been adopted

So:

• Il cane è adottabile = the dog is available/suitable for adoption
• Il cane è adottato = the dog has been adopted

In your sentence, adottabile is used because the dog is being described as a dog that could be adopted.

The accent is important because it distinguishes:

• è = is
• e = and

So:

• il cane è randagio = the dog is stray
• il cane e il gatto = the dog and the cat

This is one of the most important written distinctions for beginners in Italian.

Yes. For example:

• Il cane è adottabile anche se è randagio.

This means essentially the same thing, but the focus changes a little. The original sentence puts the contrast first:

• Anche se il cane è randagio, è adottabile.

That structure emphasizes the idea of despite being stray.

So both are possible, but the original is very natural if the speaker wants to highlight the contrast first.
