Who says animals are dumb?
This is a bit silly but here I go anyway. Have you ever wondered about dog and cats and what language they understand. If you raised a dog in an English speaking country how long would it take to understand commands in Spanish? And vice versa?

I have a spanish dog, however the interesting thing is when we took him to a dog training class in spain we were told you always teach the commands (sit, stay, roll over ) in english.
so my other half talks to him and tells him off in spanish ( he is a naughty puppy!!) and then commands him in english. He seems to understand : )
I would assume not too long. They don't have to learn the entire language, just a few synonyms for commands they already know. I could be wrong, though. I'm definitely not a dog expert.
my uncle speaks english and spanish fluently and he had a dog that understood both languages

Now that I'm in a Spanish-speaking country I'm speaking to my dog more in Spanish. She seems to understand my tone of voice, mannerisms/hand gestures, etc., rather than the words themselves.
Words she certainly understands are Pollo & Chicken!!
