hello, we did exactly the same a year ago, and took in a 2nd rescue dog (a 12 week old puppy).  In hindsight we realise this was probably a mistake.  Apart from the additional costs of a second dog, we found two dogs in the house just a little bit too much, particularly as we have children as well.  Also, you have to consider things like going on holiday, whereas a neighbour might take in one pet for you, would they want 2? I agree, that a dog walker during the day might offer a better option for your dog.  There's no guarantee that another dog would get on that well with your current one anyway!  good luck

You can do it using various image/graphic software like Photoshop / Paint shop etc - there are probably other ways but if you post the pic you would like to be smaller here - I can do it for you
