Short for "hair of the dog that bit you", which was an old superstitious cure for a dog bite. Used mostly when having alcohol in hopes of relieving a hangover.

Also a 1975 Nazareth album, and a song (listed as being written by the entire band) from it, which was later covered by Guns 'n Roses on The Spaghetti Incident. Since the title is nowhere in the song lyrics, many people think of the song as "Now you're messin' with a son of a bitch" from its chorus. The album contains:

  1. Hair Of The Dog
  2. Miss Misery
  3. Love Hurts
  4. Changin' Times
  5. Beggars Day
  6. Rose In The Heather
  7. Whiskey Drinkin' Woman
  8. Please Don't Judas Me
The song:
Heartbreaker, soul shaker
I've been told about you
Steamroller, midnight stroller
What they've been saying must be true

Red hot mama
Velvet charmer
Time's come to pay your dues

Now you're messin' with a
A son of a bitch
Now you're messin' with a son of a bitch
Now you're messin' with a
A son of a bitch
Now you're messin' with a son of a bitch

Talkin' jivey, poison ivy
You ain't gonna cling to me
Man taker, born faker
I ain't so blind I can't see


Red hot mama
Velvet charmer
Time's come to pay your dues

Now you're messin' with a
A son of a bitch
Now you're messin' with a son of a bitch
Now you're messin' with a
A son of a bitch
Now you're messin' with a son of a bitch

(pipes solo)

Now you're messin' with a
A son of a bitch
Now you're messin' with a son of a bitch
Now you're messin' with a
A son of a bitch
Now you're messin' with a son of a bitch
