Domestic dogs in Belgium showed a mean prevalence of T. canis of 4.4%, those from larger kennels of up to 31%. [6] In domestic dogs in Serbia, T. canis was detectable in 30% of the animals, [7] in herding and hunting dogs in Greece in 12.8% and T. leonina in 0.7% of animals. [8]
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
Pet owners are being warned about an unlikely danger to their dogs—lady bugs. ... a disturbing photo showing a number of the tiny black-spotted insects attached to the roof of a dog's mouth. ...
Echinococcus granulosus, also called the hydatid worm or dog tapeworm, is a cyclophyllid cestode that dwells in the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease.
Toxocara canis (T. canis, also known as dog roundworm) is a worldwide-distributed helminth parasite that primarily infects dogs and other canids, but can also infect other animals including humans. [ 1 ] [ 2 ] The name is derived from the Greek word toxon 'bow, quiver' and the Latin word caro 'flesh'. [ 3 ]
In 2014, Christenhusz and Chase grouped all the fern subclasses together as Polypodiophyta [3] and in 2016 the Pteridophyte Phylogeny Group (PPG) adopted the class Polypodiopsida sensu lato for the four fern subclasses. The following cladogram shows the phylogenic relationship between the subclasses according to the PPG.
The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized 13 genera. [5] Shortly afterwards, the genus Gastoniella was created for three species formerly placed in Anogramma which a molecular phylogenetic analysis had shown to be distinct.
Lycopodioideae is a subfamily in the family Lycopodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [1] It is equivalent to a broad circumscription of the genus Lycopodium in other classifications. Like all lycophytes, members of the Lycopodioideae reproduce by spores.
