I'm sorry, I can understand how you must miss him! But, I'm sure he will remember you! I don't think my dogs have ever forgotten anyone, ever, who has given them food! Imagine how overjoyed Sammy will be to see you!

When I studied abroad for a summer I was afraid that Marta would forget, me, too. But she didn't! Sammy will probably do a cartwheel when he sees you next! And remember, he's in good hands with your dad!
