I had my last bitch spayed but as yet, I haven't had my 14 month old collie done. She's had one season and wasn't at all "distressed" as someone put it! My other (male) dog is neutered (medical reasons) so, because I keep Meg under control, there's no danger of unwanted pups. I'd like to add that a friend of mine has 2 bitches (mother and daughter), both unspayed. The daughter was deliberately mated just before Xmas and now they can't find homes for all the pups. They "don't believe in spaying", despite advice. I'll probably get Meg done when she's a bit older.
