When I got Ali at 8 months, I had an 8 month old Golden Retriever (Disco). I was very worried that I would have way too much "puppy energy" on my hands, but the two of them balanced each other out very nicely. That was, until they both came into season at the same time. Then, there was double the trouble and they both chewed up my favorite pair of pink high heels.
Ali was a great playmate for Disco and taught her a thing or two about playing. Disco just about flipped out of her mind when Ali first started to box with her. After a few times, Disco started to figure out that Ali was playing, so she started to do it too.
Disco was soft dog and pretty much let Ali do whatever she wanted. Ali jumped over her and under her, tugged on all of her extra hair, but at the end of the night, they would both snuggle up next to one another and dream the night away.
