I was just talking with my friend(she's over at my house) and then she started breathing really fast,like panting. When I placed my hand over her heart,I could feel it thump madly. She said her heart hurt and she felt like she could barely breathe. Is this bad?

My Grandma has a beautiful Golden Retreiever/Aussie mix,whose name is Annie. She's about 2 or 3 years old. Today I was brushing her and her hair was filling up the brush. I noticed some of her fur sticking up and it was very noticable. I tried to flatten it,and remembered my dog back at home. Some of her fur on her rump had turned brown,and I was able to pull the brown-colored fur(which was very noticable against her black fur) in small tufts. This is what's happening to Annie. I pulled some of this sticking-out-fur out of her coat in little tufts. The fur is very soft. When I pulled out some of the fur,she showed no signs it hurt. Is this natural? Is she just shedding her winter coat? Or do I need to take her to see a vet?

Two days ago I had sent an e-mail to my friend. We were just getting over our troubles and we were getting very close again. The e-mail I had sent was nice and showed no signs I had tried to insult her. At the end I had put "love" then my name,as we always did(it was friend love). Last night I got an e-mail in reply that said,"Get a life and quit being lesbian". I was so confused. I sent an e-mail back questioning it,and I got a reply about 2 or 3 hours later. It was from my friend this time. It said something along the lines of: "Who sent you this? Someone must have hacked me...my computer is getting worked on." I believe her...I don't think she would purposely send me an e-mail claiming I was lesbian. But I must know: Could her e-mail have gotten hacked?
