Am I being totally ridiculous over these worries; stressed that rescue dog may never get on with other dogs, even though i am going to have one to one help after neutering op, next, that dog will never be able to go off lead in garden because he harasses the guinea pigs and I am afraid they are going to have a heart attack, next, that if anyone ever let's him out of his crate when he is barking that he will always bark to get out, and finally that, when we go on holiday in summer without him and he is at the dog minder that I will never get him back into his routine. She has dogs, early risers, 6 am. I know this may sound silly, but it is all really playing heavily on my mind.
