Hi, I have my first Berner puppy, now 8 months old. We live in the UK so have a temperate climate & our Berner is our only dog. I was just wondering how much variation there is between Berner bitches & their first season & when I might expect her first one. I know what to look out for physically, but are there any other signals I could watch out for (someone suggested she may start sleeping a lot more) other than spotting and swelling? Thank you.
