Friedrich Urech synthesized 5-methylhydantoin in 1873 from alanine sulfate and potassium cyanate in what is now known as the Urech hydantoin synthesis. [2] The method is very similar to the modern route using alkyl and arylcyanates.
Ethylene glycol, antifreeze, is extremely toxic to dogs. It has a sweet taste and thus dogs will drink it. As little as 2 1/2 tablespoons can kill a medium-sized dog in 2–3 days. This type of poisoning is often fatal as dog owners do not know their pet has ingested the antifreeze. De-icing fluids can also contain ethylene glycol.

This is a collection of articles about the health and care of dogs, primarily domestic dogs. This includes medical conditions, health issues, parasites, surgical procedures, and similar topics. The main article for this category is Dog health .
Additionally, chronic toxicity tests tend to require significantly more attention and resources than acute tests which makes them much less feasible for basing decisions off of in a timely manner. The need for development of more advanced statistical methods, and uniformity in using these methods by regulators has been made apparent in literature.
Sudden acquired retinal degeneration syndrome (SARDS) is a disease in dogs causing sudden blindness. It can occur in any breed, but female dogs may be predisposed. [1] Approximately 4000 cases are seen in the United States annually. [2]
A study of 66 dogs with Cushing's found 91% of dogs to have either polyuria or polydipsia, 79% to have polyphagia, and 77% to have alopecia. [ 4 ] Signs of ectopic adrenocorticotropic hormone secretion that accompany the rapidly progressing physical changes are high plasma levels of adrenocorticotropic hormones and cortisol alongside hypokalaemia .
