Anyone knows this anime?

I watched this movie when I was so so little. I remember it but can't find it or the name of it. My father was obsessed with anime so we would rent them in the nearest blockbuster. Anyways Iv been trying to find it and can't.

It starts like:

I think it was the child's birthday and he made a wish. (I think its too vivd this part)
The dog is able to speak now.
I don't remember the middle of the movie but she has this ability to understand her dog.
The end, ends with the weather being snowing, and she no longer can understand the dog. I guess her ability goes away. And its this really sad scene when she can't understand her dog anymore.


I remember the dog was small and white.
The kid, not sure if boy or girl. I think they were an only child in the movie.


I know its way to broad but please help me out! I was way to young to even understand the plot of the story so any guesses would help.
Anyone knows this anime?
