Although a dog's paws are protected by a layer of keratinized tissue, it is still possible for them to develop a fungal infection.

Ringworm is a fungal skin infection that causes alopecic lesions with scaling and redness, usually starting on the head and later spreading to other parts of the body.

Cockroaches are arthropods which are capable of transmitting diseases.

The normal body temperature in cats fluctuates between 38ºC and 39.5ºC (100.4ºF and 103.1ºF). When the internal body temperature of a cat exceeds this top parameter they have a fever. A cat will have a fever due to their health being impaired, usually due to their body fighting an infection of some sort....
While it is an invasive procedure, spaying your dog has a range of benefits. Their lack of ability to become pregnant prohibits the birth of puppies we don't have the resources to care for and thus reducing the cases of abandoned pets which need shelter care.
