All toads secrete mucus through the skin that does not taste good to other animals. Some toads, however, are actually poisonous. These include the tropical toads Bufo alvarius (Colorado River Toad) found in the Southwest desert and Bufo marinus found in Florida and Hawaii. Some other species of Bufotoads in other areas of the U.S. produce a milder venom. There is one species of poisonous salamander, the California Newt, which is found in California.
Tonsillitis

Dogs have tonsils like humans do. Dogs have one set of tonsils: one tonsil is located on each side of the throat. They are found within a fold of tissue referred to as a tonsillar crypt. The tonsils are part of the lymphatic system. They can become inflamed, and when they do, it is called tonsillitis.
Numbers and Types of Dog Teeth
Types of teeth
Mammalian carnivores have teeth that line the upper and lower jaws. There are four types of teeth with different functions:
- Incisors: cutting and nibbling food
- Canine teeth: holding and tearing food
- Premolars: cutting, holding, and shearing food
- Molars: grinding food
Numbers of teeth
Many mammals, including dogs are “diphyodont” meaning they have two sets of teeth, one set (called “deciduous”) being shed and replaced by a permanent set. Although the exact number can vary, puppies have 28 deciduous (temporary) teeth, and adult dogs have 42 permanent teeth.
Tooth eruption
In puppies, the deciduous teeth begin to erupt at about 3-4 weeks of age and the permanent teeth begin to emerge at about 3-4 months of age. By 24 weeks of age, usually all of the permanent teeth have emerged.
| Animal | Number of Deciduous Teeth | Number of Permanent Teeth | Age at Eruption of Deciduous Teeth | Age at Eruption of Permanent Teeth |
|---|---|---|---|---|
| Dog |
28
•14 upper |
42
•20 upper |
3-8 weeks | 12-26 weeks |
A deciduous tooth should be lost before its permanent replacement appears. When a carnivore has both a permanent and deciduous tooth at the same site, it is referred to as a “retained deciduous tooth.” These need to be removed surgically to prevent abnormal alignment of the permanent tooth.

Tooth Anatomy
Tooth anatomy
Each tooth has a crown (located above the gums) and a root (located below the gums). Some teeth, such as incisors, have one root, while others, such as the largest cutting premolar, called the “carnassial tooth,” has as many as three roots. A tooth is composed of the following structures:
Torn Nails

The nails of the dog are basically an extension of his skin. Nails are composed of hardened (cornified) epithelial (skin) cells arising from the ungual crest or nail bed. The toenails of a puppy tend to be more pointed and sharp as compared to adult nails. Their rapid growth rates and sharpness require frequent trimming, sometimes more than once a month.
Tracheal Hypoplasia

Occasionally, puppies are born with a trachea (windpipe) that is not as rigid as it should be. With tracheal hypoplasia, the normally strong cartilage rings that support and keep the trachea round and open are instead weak and underdeveloped, therefore, providing little rigidity.
