💡 Grammar Points
Masculine and Feminine Forms
Like many Spanish nouns for people or animals, 'perro' is masculine. To talk about a female dog, you just change the ending to '-a': 'una perra'. The plural is 'perros' for a group of male dogs or a mixed group, and 'perras' for a group of all-female dogs.
❌ Common Pitfalls
Pronouncing the 'rr' Sound
Mistake: "Saying 'pero' with a single, soft 'r' sound, like in the English word 'butter'."
Correction: Make sure to roll or trill the 'rr' in 'perro'. The word 'pero' (with one 'r') means 'but', so getting the sound right is important to avoid confusion!
⭐ Usage Tips
Showing Affection with '-ito'
Spanish speakers love to add '-ito' to the end of words to show affection or smallness. You'll frequently hear 'perrito' to mean 'puppy' or just 'little doggie'.

In informal contexts, perro can be used as a strong insult meaning 'jerk' or 'despicable person'.
📝 In Action
No confíes en él, es un perro.
B2Don't trust him, he's a dog/jerk.
¡Qué perro! Me mintió todo el tiempo.
B2What a dog! He lied to me the whole time.
❌ Common Pitfalls
Using the Feminine Form 'Perra'
Mistake: "Thinking 'perra' is a simple equivalent insult for a woman."
Correction: Be extremely careful. While 'perro' is a strong insult for a man, 'perra' is a much more offensive and vulgar insult for a woman, often with strong sexual connotations. It's best to avoid using it entirely.
⭐ Usage Tips
Context is Everything
This meaning is always clear from the angry or negative tone of the conversation. You would never use it neutrally. It's a strong insult, so use it with caution, if at all.
