The best way to reduce the likelihood
of a male dog becoming a urine
marker is to have him neutered at a young age, before he develops
territorial behavior.
Three principles should be kept in mind: 1) Once a cat starts scratching an object she tends to return to it; 2) prominent objects - which make the best
territorial markers - are favored, and 3) the texture
of a potential scratching area influences whether it is used or not.
