Question: The Chesapeake Bay Retriever and Newfoundland are both breeds of what?
Context: Chesapeake Bay Interpretive Buoy System (CBIBS) is a network of observational buoys that are deployed throughout the Chesapeake Bay to observe the estuary's changing conditions and to serve as way points along the Captain John Smith Chesapeake National Historic Trail.  They are maintained by the United States National Oceanic and Atmospheric Administration (NOAA).  These "smart buoys" observe and record meteorological, oceanographic and water quality data which can be obtained in real-time by calling 1-877-BUOY-BAY or by logging on to http://buoybay.noaa.gov/.  CBIBS is an operational buoy system in the Chesapeake Bay dedicated to maintaining a broad range of measurements necessary to track Bay restoration progress. The Great Chesapeake Bay Schooner Race (GCBSR) is an annual schooner race established in 1990 that takes place on the Chesapeake Bay.  The race—held in October of each year—begins just south of the Chesapeake Bay Bridge near Annapolis, Maryland, and ends at Thimble Shoal Light north of the Hampton Roads channel, covering 127 nmi .  Pre- and post-race activities take place in Baltimore, Maryland, and Portsmouth, Virginia, respectively.  Proceeds from the race support Chesapeake Bay education and preservation projects.  The current time to beat is 11 hours, 18 minutes, 53 seconds and was set in 2007 by the schooner "Virginia". The Chesapeake Bay Retriever is a large-sized breed of dog belonging to the Retriever, Gundog, and Sporting breed groups.  Members of the breed may also be referred to as a Chessie, CBR, or Chesapeake.  The breed was developed in the United States Chesapeake Bay area during the 19th century.  Historically used by area market hunters to retrieve waterfowl, it is primarily a family pet and hunting companion.  They are often known for their love of water and their ability to hunt.  It is a medium to large sized dog similar in appearance to the Labrador Retriever.  The Chesapeake have a wavy coat, rather than the Labrador's smooth coat.  They are described as having a bright and happy disposition, courage, willingness to work, alertness, intelligence, and love of water as some of their characteristics. The 2005 Chesapeake Bay crossing study (also known as the Task Force on Traffic Capacity Across the Chesapeake Bay) was a study conducted by the state of Maryland in 2005 in order to explore the possibility of building a new crossing of the Chesapeake Bay.  The crossing would either be an entirely new crossing that would complement the existing Chesapeake Bay Bridge and Chesapeake Bay Bridge-Tunnel in Virginia or would be an upgrade to the current Maryland crossing (by adding a third span). Macoma tenta, the narrowed macoma clam or elongate macoma is a species of clam, a marine bivalve mollusk (bivalvia) in the family Tellinidae and genus Macoma.  Macoma tenta are one of two species of macoma clams that can be found in the Chesapeake Bay on the eastern shore of the United States in Maryland and Virginia.  The macoma tenta like their cousin in the Chesapeake, the Macoma balthica or Baltic macoma clam, are small marine bivalves with thin, chalky white shells.  They tend to live buried in the sandy or muddy areas of shallow water in the middle and lower Chesapeake Bay.  Macoma clams are among the most abundant clams in the Chesapeake Bay.  Macomas first appeared about 750,000 years ago. Twelve states of the United States have designated an official state dog breed.  Maryland was the first state to name a dog breed as a state symbol, naming the Chesapeake Bay Retriever in 1964.  Pennsylvania followed the year after, naming the Great Dane as its official breed.  Dog breeds are mostly affiliated with the states that they originated in.  North Carolina chose the Plott Hound as it was the only dog breed indigenous to the state. The Chesapeake Bay Trust is a non-profit organization established by the Maryland General Assembly in 1985.  Its mission is to support restoration and environmental education efforts that improve the health of the Chesapeake Bay watershed and Maryland's other natural resources.  The organization makes millions of dollars in grants per year.  The organization receives no public tax dollars.  It is funded primarily through sales of commemorative Chesapeake Bay license plates, voluntary donations to the Chesapeake and Endangered Species Fund, and partnerships with other funders and foundations.  Headquartered in Annapolis, Maryland, the organization has repeatedly received four stars (the highest possible rating) from Charity Navigator, an independent charity evaluator. The Chesapeake Bay Program is the regional partnership that directs and conducts the restoration of the Chesapeake Bay in the United States.  As a partnership, the Chesapeake Bay Program brings together members of various state, federal, academic and local watershed organizations to build and adopt policies that support Chesapeake Bay restoration.  By combining the resources and unique strengths of each individual organization, the Chesapeake Bay Program is able to follow a unified plan for restoration.  The program office is located in Annapolis, Maryland. The Newfoundland dog is a large working dog.  They can be either black, brown, or white-and-black (called Landseer).  However, in Canada, the country of their origin, the only correct colours are either black or Landseer.  They were originally bred and used as a working dog for fishermen in the Dominion of Newfoundland (which is now part of Canada).  They are known for their giant size, intelligence, tremendous strength, calm dispositions, and loyalty.  Newfoundland dogs excel at water rescue/lifesaving because of their muscular build, thick double coat, webbed feet, and innate swimming abilities. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).  Onset is typically after the age of 7 years and it is seen most frequently in the German shepherd dog, Pembroke Welsh corgi, and boxer dog, though the disorder is strongly associated with a gene mutation in SOD1 that has been found in 43 breeds as of 2008, including the wire fox terrier, Chesapeake Bay retriever, Rhodesian ridgeback, and Cardigan Welsh corgi.  Progressive weakness and incoordination of the rear limbs are often the first signs seen in affected dogs, with progression over time to complete paralysis.  Myelin is an insulating sheath around neurons in the spinal cord.  One proposed cause of degenerative myelopathy is that the immune system attacks this sheath, breaking it down.  This results in a loss of communication between nerves in lower body of the animal and the brain.
