hi there just like to ask a quick question, one of the lads a know had his 4 year old lurcher dog castrated a few weeks ago, he never had really much of an option as he keeps 2 terrier bitches as well and every time they come in to season the lurcher goes crazy howling the place down, which is normal but it came to the point neighbours have reported him for the nosies, so he decided to get him castrated ,more to the point do you think that the dog will still have the fire in his belly when it comes to a hard day or nights grafting away on charlie etc
