Some of the most notable recent trends in the past decade include:
- The most popular pets with the biggest increase in rankings over the last decade included the Bulldog (from 21st to 7th); French Bulldog (from 73rd to 24th); Cavalier King Charles Spaniel (from 58th to 25th) and the making the largest leap the Havanese (from 92nd to 32nd).
- Working K-9 breeds favored by law enforcement and the military have shown modest gains as pets including the Belgian Malinois (from 95th to 81st), the Border Collie (from 71st to 52nd) Bloodhound (from 51st to 43rd), and the Doberman Pinscher which served heroically with the U.S. Military during WWII (from 23rd to 15th).
- A trend toward easy-to-groom breeds is seen with the rise of the Mastiff (from 39th to 27th) and the Rhodesian Ridgeback (from 56th to 48th) as well as the decline of higher maintenance breeds such as the corded breeds the Komondor (from 132nd to 154th) and the Puli (from 123rd to 149th) and on the Irish Terrier (from 108th to 132nd) and Sealyham Terrier (from 138th to 157th) which require hand-stripping.
- Among rare breeds on the decline are the Curly-Coated Retriever (from 114th to 142nd), the Sussex Spaniel (from 135th to 159th) and the Irish Water Spaniel (from 130th to 150th).
- Even before the Obama family selected the Portuguese Water Dog it was on the rise in popularity ranked 80th a decade ago to 60th currently. However, it did make a jump from 64th a year ago when all the interest in this mid-sized, hypoallergenic breed began.
