I am a PhD student at Karolinska Institute, who extremely likes dogs. By the way, border collie is my favourate, although I like most dogs as a dog person.
Unfortunately, I don't have a chance to have a dog by myself especially a big-size dog, that's why I don't have much experience to take care of dogs, but I can handle it because my close friends have dogs and I often play with them. I also help them to walk dogs occasionaly, and play frisbee or balls.
I am not a vet, but I am a medical student, not sure weather can offer help when there is some emergence happened. Of course I don't hope it take place.
I can come to your place to take care of dogs, and I have my own small apartment where I can stay with them as well when they are used to the new environment.
It's beetter to have vaccine.
