Morning all,
Just came back in house after enjoying another late cup of coffee out back.
Out back under 9" umbrella at table is enjoyable for me anytime.Early morning 4 or 5ish,is "Bears" first time out.Now it has become a time for "Ms Paws" also.She has been curious about what goes on out there......so with harness and lead,she now asks to sit in my lap OUTSIDE.Understand she is a house cat only.She learns the rules (in our lap only,no lunging for geckos,low flying birds etc)very well and is doing great.
Where was I....oh ya...just came in after watching the squirrels (about 8 or 9 )playing and running in my large tree along border fence.Very entertaining to say the least.They drive "Bear" up the wall,with their antics.
I hung 2 bird feeders out to catch some photos of birds,which I'll post here next time.The bird feeders have been quite a challenge for the squirrel population.They are both advertised as "Squirrel" proof,and have so far lived up to the labeling.
Pictures to follow.
Bob
PS: Finally getting some much needed rain.

Dog's Eating Mechanics
The Dog’s Mechanics of Eating
Oct.05, 2006 in Dog Nutrition
Many dog owners think that every different breed of dog must be fed different, according to some sort of specification. However, the eating behavior of a dog is characteristic of the whole species, not of any individual breed, since all dogs eat the same way. As a result, there are certain general considerations that can be made when feeding any dog.
A dog is not required to eat its food the same way a man does. A dog has no hands. It's jaws are suited for biting and cutting rather than chewing. There are few "gag" reflex nerves at the back of a dog's mouth, but many in a person's throat. A dog has fewer taste buds on its tongue, but a much greater sense of smell than a man has. There are many other differences as well.
How A Dog Eats
While the eating behavior of a dog may seem strange or awkward to some dog owners, to the dog it is the most comfortable and satisfactory way of getting its food from its bowl into its stomach. The normal pattern of swallowing in a dog is often described as "bolting." The dog picks up a piece of food with its front teeth and with a short, quick thrust of its head, tosses the piece of food back onto the top of its tongue. The piece of food is then rolled (without being chewed) to the back of the mouth. As the piece reaches the base of the tongue, a reflex causes the back of the tongue to push the food upward and backward into the esophagus. From there it is carried directly into the stomach.
When a piece of food is too large to be swallowed, the dog holds the food with its paws and uses its front teeth to tear off smaller pieces that can be swallowed. If the food is too tough to be torn, the dog will cut it into pieces small enough to be swallowed, using two specialized jaw teeth.
These teeth are called carnassial teeth and have large shearing surfaces that act like scissor blades which can cut through such tough substances as muscle, hide, gristle, and even bone. While the powerful jaw muscles of a dog are useful for cutting chunks of food into swallowing size, these muscles are used very little for actually chewing those pieces. A dog's teeth are few in number and poorly equipped for mastication.
