Biscuit just got over his cough and I am wanting to nueter him.He still coughs occasionally, but for those of you who have had or are having experience with chronic cough in Yorkies, are your babies spayed/neutered? Did it make there cough worse to go under with a trach tube? I am worried that his throat will be irritated and his cough will come back 

 It took so long to go away!) 
If I wait too long to neuter him, how will he be different that if I do it soon?More marking? 
Thanks for any help
