My best friend owns a nearly 3 year old Australian Shepherd which is a desexed female. The dog is very clingy towards her (what we call a glad wrap dog but on the other hand it is more of a "dog dog" than a "person dog". She is thinking about getting another Aussie and she has a few issues. One is that someone told her to get a male dog because male and females get on better? So what do people think, is a male female relationship better between two dogs or is it better when they are the same sex? My opinion is that if they are both desexed and socialised they will get on regardless of the gender.
The other issue is, that she is worried her dog will get jealous of the new one and start bad habits like barking, digging etc. The dog currently resides with an 8 year old Cavalier that does not interact with the younger dog in any way. Any suggestions?
