 are followed by a white-space character and the string "is", which ends on a word boundary. Suppose, I have a following string: What I want it to do is, capture every single word, so that Group 1 is : "HELLO", Group 2 is "THERE" and Group 3 is "WORLD" What my regex is actually capturing only the last one, which is "WORLD". This is the second capturing group. RegEx Module. The following grouping construct applies or disables the specified options within a subexpression: where subexpression is any valid regular expression pattern. This option is recommended if you know that backtracking will not succeed. The regular expression pattern's two capturing groups represent the two instances of the duplicated word. The following example illustrates a regular expression that identifies duplicated words and the word that immediately follows each duplicated word. "subexpression) language construct disables backtracking. The regular expression \b(? Matches the left angle bracket in " ( ).

Try a different brush! I was surprised how much easier  it was when I switched brushes. I got this one linked below which I use more frequently. And then every few days I use a slicker brush and/or comb. The small brush doesn't hurt him so he enjoys the brushing and the treats that follow. I follow the exact same routine for the other brushes and because he is used to it he doesn't complain. 

And more importantly, just give it time!
