Was on the phone with my BF yesterday. They have a pug and a miniature poodle, neither spayed or neutered. Her Hubby wouldn't let her get them fixed. Well...........now there may be puppies. And the male is watering everything. Her Hubby has changed his mind but the damage may be done and SHE'LL have to deal with it. She was looking for a place to get the poodle neutered and yelled "He peed on the phonebook!" LOL
That is a nightmare! We had an intact male and female in our house for about four years. The howling, the marking, the manic behaviour was nonstop for weeks twice a year. Never again.
