Only Find Word After a String?

VB

Hello I am using regex or regular expressions in vb.net and need to learn how to use look ahead to only find the word that comes after a string.

for example

This is the text string: Dog


My problem here is that if i write my regular expression as follows

[This is the text string:] \w+

it will find the string and the word but it will also find other matches of the word dog if they exist. I need to only find the word "Dog" if the string before it is "This is the text string:"

Any help or examples would be greatly appreciated or if anyone can tell me how to find a entire string but exclude everything except the word "dog"

thank you in advance!!
