Hi, Rusty!
It is nice that your son's dog and her sister are able to meet up !
Our dog has two brothers, but they left Battersea Dogs' Home before she did, and so we never met them.
Their mum - a spaniel, and already pregnant - was found tied up on a deserted gipsy site, and was then taken to the Battersea Home.
We got our puppy at seven weeks old.
She is now eight years old.........wherever do the years go?
I have looked at the clip about honeyberries.
A honeyberry is described as a cross between a raspberry, blueberry and blackberry, perhaps with a touch of elderberry and added "zing"!
It sounds delicious!
Maybe you can buy some from the nearby farm, and try them?
