PENNELLVILLE, N.Y. -- Adam Capenos owns Ann Margarete's Kennels. He says area animal hospitals have recommended his services for years and that most of his business is from happy, repeat customers.

"I'm not just talking about single pet owners. I'm talking about generations of dogs that have come to us. Seventy-five percent of our customers come here three to four times a year," said Capenos.

Dara Rosenthal and her boyfriend, RJ, had a bad experience when they left their dog Adonis, who they call Doney, at the kennel for about three weeks, beginning in mid-December. They say when they picked the dog up, he was severely dehydrated and lethargic.

"When I called and asked if the dog was eating, they said he was eating fine," said Rosenthal.

Vet records given to us by Rosenthal show that Adonis weighed about 29 pounds initially and lost 7.6 pounds by the time he was picked up and also state that he was severely undernourished and extremely thin. But Capenos says the dog was active and healthy while he was at the kennel.

"I mean, Adonis was fine. Hyper, but fine. Ate everything we gave him, always had water and seemed like nothing was wrong," said Capenos.

Rosenthal says she called the kennel multiple times while she was away to check up on her dog and was told he was doing well. And Capenos maintains that Adonis was perfectly fine during his stay.

"He did not appear any different the day he came in to me. We didn't mistreat him at all," said Capenos.

Capenos says he thinks the dispute over the dog's health boils down to Rosenthal and her boyfriend being unable to pay the kennel bill of more than $450.

"They presented us with two different credit cards and said they only have $300 available to them and they were adamant that's all they had," said Rosenthal.

But Rosenthal says she always intended to pay the full bill and that she wasn't sure if she and her boyfriend would split it or put it on one card.

"We decided to split it, but after I remembered I had this other credit card and it didn't matter," said Rosenthal.

Since our report on the kennel first aired, about a dozen viewers e-mailed us, most praising the work of the kennel and the work done there over the last 29 years.

The vet who cares for Adonis did not want to comment on the case.

Rosenthal has filed a report with the Oswego County Sheriff's department to try to get back the money she paid for the kennel services and the vet bills.
