Lurcher Lollops, and Bull Terrier Thrills - Football on the Beach

Our dog, Barley the Lurcher, is built for speed. He thoroughly enjoys a running about like a dog possessed.
Mr.R likes walking, and so do I, it's enjoyable exercise and healthy.
So in order for us to get some fresh air, and to let Barley have a good long run, we recently took him to a local beach.
A friend joined us with two of his Bull Terrier dogs, Mandy and Gracie.

We took a football with us, and all three dogs had lots of fun chasing it across the sand.
Unfortunately the ball didn't last long, although it survived much longer than we expected, it suffered a fatal puncture wound, and sadly died.
Mr.R had won the football, so at least it didn't cost us any money. Haha!

Barley, Mandy, and Gracie never stopped, running, play-fighting, chasing the ball, and generally having a blast on the beach.
A good day was had by all of us.
I always feel good when I'm by the sea, it helps calm my mind, so being on the beach was bound to be a winner. And watching the dog have lots of fun was excellent.
