Why do dogs sometimes travel in packs?

Dogs usually travel in packs, that is one reason they make such great pets.  They come to view their human family as their pack mates.

It depends entirley on hair colour, most adapt so that they blend in, but you can see them moving if there are lots, mostly they cling on to the hair as they find it very difficult to move out of hair. I have provided some links to close up pics of the beasties!

I don't know, but why not? They dream. Dogs twich when they dream about chasing something, they also run in their sleep, and growl.

I think it has a lot to do with how people fed them when they were young.  Animals that were not fed frequently enough during the day were famished when food was put before them, so they learned to eat quickly everything that was set in front of them.  In the book I got for raising my puppy, it said to leave food out for him all day long, that way he would never get super hungry and gulp his food.  He is now four years old and only gets fed once a day.  He eats half of the food in his bowl before his walk and when he gets back he eats the other half. Some days he chooses to not finish his dinner and I end up throwing it away.\nSo I guess animals are a lot like humans... if you establish good eating habits when you are young, it serves you well your whole life.

Humans ask questions to communicate, to satisfy their needs, wants and curiosities. This may just be my opinion, but I think that animals ask questions. When your dog or cat goes to the door and scratches on it or whines, you know they're saying, "Can I go outside"? "Do you really want a cleanup in aisle #3?" When your dog gets his leash and brings it to you, you know he's saying, "Can we go for a walk, please". My mother had a goldfish that would come to the top of the water when he wanted to eat. Was he asking for food? HMMMM

Because energy is wasted everytime it is passed on from organism to organism, so it's just not efficient for an animal to eat a high up animal when the less high up animals have more energy.  Something would have to eat a lot of humans, for instance, to be full up.

some of them might hibernate. hibernation allows some small mammals to reduce their metabolism during times of scarce resources, such as winter. they accumulate body fat for a while, then it's like their system «shuts down»: their body temperature decreases, their pulse too, and they might breathe as few as 1 to 10 times a minute!\nhibernation is a real advantage because, when it's cold, it would take a lot more energy to keep normal body heat, consuming more nutrients, when, in fact, it's the time of year when it's more difficult to feed!

Yeah, they're all talking about their favorite all-time baseball player, where they can find house shingles, and the stuff on the outer layers of those trees they mark. ; )\n\nSeriously, I don't know if it's conversational in nature, but probably more of a territorial thing: they bark to let other dogs know they're around and as a warning to not trespass. My guess is that when the last one barks, he/she knows the other dog "left."

My dogs bark. He's only like thiry pounds but he has a set of lungs on him. he is so dramatic when he barks, and he has to bark everytime he gets a chance. He always has to let me know when their are kids playing out side, or some one gets home, etc. I have tons of thow pillows just for this reason. He is scaird of them so i just thow one toward him, and he shuts up.

Yes, they are. Animals are sent to space for various reserch purposes, and examined upon return. Not returning them will undermine the very purpose of sending them in the first place.\n\nOne of the answers above says that they are not returned if they are sent alone. It happens only if something goes wrong; but at all times they are intended to return. For example, russians sent a couple of dogs to space before launching the first human. When the dogs safely returned, it was concluded that it is safe to send a human being. Not returning the dogs to check on them would have made no experimental sense.\n\nSadly, as you know, humans not always return; the same applies to animals. For instance, space shuttle "Columbia" had on board several laboratory rats returning to Earth together with the astronauts. We  know the end of that story...

I believe they carry them back to the nest where they are eaten for nourishment. To them its just protein and its much easier to come by

Probably walked, or rode a horse, or by ship.  Many different modes of transport.

You just make sure that the things in the pack are waterproofed. the air that is trapped in the packaging provides positive buoyancy to the pack which allows it to float.

Bear. Wolves are pack animals and it's pretty hard to outwit a determined group of anything that's working as a team (this applies to sports teams and kindergarteners looking for mischief). Besides, bears are pretty lazy and unless you're in the same vicinity as their young or after their dinner, they're usually content to go their way while you go yours.\n\nHad an encounter with a bear on a mountainside in Tennessee once. I think we scared him as much as he scared us, and we all parted (quickly) as friends.\n\nBest,\n~Tia~

It depends on the species. Some will travel very far to follow, or find, food. Some will travel during different seasons.

Ew.  You have a rat.  Not sure about rats.  Dogs go though.
