For a precise split, you could use #\\$& to match all 3 characters where the dollar sign has to be escaped, and the backslash itself also has to be escaped.

val s1= "dog#$&cat#$&cow#$&snak"
val s2= s1.split("#\\$&")

Output

s2: Array[String] = Array(dog, cat, cow, snak)

A broader pattern could be using \\W+ to match 1+ times any character except a word character.
