They may be an unusual match but this dog and duck are the best of friends.

Four-year-old Pekin Andy and golden retriever Barclay are inseparable despite their love/hate relationship.

Proud owner Pam Ishiguro, from Orange County, California, says the animals always call for each other whenever they are apart.

She said: ‘The animals are much like my two boys – they have a love-hate relationship.

Inseparable: Any and Barclay often snuggle up to one another as they play at their home

Relaxing: The two animals often enjoy their down-time together on the floor or the sofa

‘When they are together, somebody is always chasing or jumping on someone else, but when they are apart, they’re always calling for each other.

‘Barclay loves to eat duck chow – actually he just likes to eat and knows there’s always food in the coop, so whenever he gets a chance, he’ll sneak into the coop and eat their food.

‘He also likes to drink their bath water and, if he happens to be stealthy enough, he loves to sniff a little duck butt.’

But the dog and duck pairing was not always so friendly. At first Rudy enjoyed chasing Barclay away whenever he tried to approach any of the ducks in the group.

Miss Ishiguro explained: ‘Rudy is our alpha duck. He is in charge of everyone and everything.

‘When Barclay tries to sniff any of the other ducks, Rudy is there to stop it. Rudy used to chase Barclay away, and for a long while, Barclay would run away.

‘Just recently, however, Barclay has decided that he’s no longer afraid of the ducks, or perhaps the appeal of getting a bite of their food is so strong that it’s given him more courage.

‘Now Rudy has to ‘claim’ Barclay every once in a while by climbing on top of him. Barclay doesn’t seem to mind terribly because that gives him the opportunity to sniff Rudy’s butt – win-win!’
