With the ship in the port of Gdynia on Friday, the black-and-brown mongrel was occasionally taken on land for walks, he said.

Nicknamed "Baltic," the dog -- furry and friendly -- will continue in that capacity unless his owner is found, the captain said. The ship is preparing to sail Feb. 10 on a brief mission -- with the dog, unless he is afraid, Wosachlo said.

"We have enrolled him as a crew member," Wosachlo said.

Jerzy Wosachlo, the captain of the Baltica, said the dog slept on a blanket in the ship's laboratory, then shared a sausage breakfast with the crew. He said the dog often sticks close to the mechanic who saved him but also has started moving around as he pleases, enjoying the company of people.

WARSAW — A dog rescued from the Baltic Sea after braving a 75-mile journey on an ice floe is making himself at home on the Polish research ship whose crew rescued him, the captain said Friday.

The Sea Fishing Institute that owns the ship sent a bowl and a squeaking toy, and the scientists on board brought dog food. And Wosachlo was receiving numerous calls from people offering money to feed the dog or wanting to adopt him.

After news of the dog's rescue broke, four people called saying he was theirs. But the dog kept his distance from the first two, showing no recognition. Two other putative owners who had planned to come for the dog Friday canceled, Wosachlo said.

President Lech Kaczynski, himself a dog owner, sent the crew a letter praising its action in saving the dog's life.

"Such gestures make our world a better one," Kaczynski wrote.

The dog was first seen Saturday on the Vistula River, 60 miles inland, drifting on a piece of ice past the city of Grudziadz. Local firefighters said they failed to save him then.

He was spotted again Monday, 15 miles from land in the Baltic Sea, when he was rescued by the Baltica's crew.

The rescue was difficult because the dog kept falling into the water. Fearing he could drown, the crew lowered a pontoon to the water and the mechanic, Adam Buczynski, managed to grab the dog by the scruff of the neck and pull him to safety.

In port, the 44-pound dog was taken to a veterinarian, who found him in surprisingly good condition and estimated he was 5 or 6 years old.

The veterinarian, Aleksandra Lawniczak, said a dog with thick fur and a layer of fat can survive cold conditions for as long as eight days if it has water to drink.
