Puppy from Beethoven's 2nd Movie?

Beethoven 2nd Movie

@Pamela is probably right. They might have given that pup a certain color to make it stand out and give it personality. And FYI, 200 different Saint Bernard pups were used in that one movie (they grow really fast)! For example, my niece watches a show called "Dog with a Blog". The dog is actually white with fawn patches, but the fawn patches are dyed black and brown to add character and make him more appealing.

It is undesirable in the standard: "Color: White with red or red with white, the red in its various shades; brindle patches with white markings. The colors red and brown-yellow are of entirely equal value. Necessary markings are: white chest, feet and tip of tail, noseband, collar or spot on the nape; the latter and blaze are very desirable. Never of one color or without white. Faulty are all other colors, except the favorite dark shadings on the head (mask) and ears." -AKC standard

But it is probably just a mis-marked pup. You can even get the occasional purebred Labrador that is born brindle or with tan points. Color genetics are a bit tricky and faults can hide for many generations before popping back up.

It is very well possible for makeup to have been used to cover the blaze up.

he/she didn't get the gene for the blaze.
