Over a period of 54 months, 3518 dogs and 3806 cats were castrated; 240 of the dogs and 50 of the cats were cryptorchid. Pedigree dogs, in particular the German shepherd dog, boxer and chihuahua were overrepresented. Among the dogs, right-sided inguinal cryptorchidism was the most common form, followed by right-sided abdominal cryptorchidism. The location of the affected testicle(s) was most variable in the boxer. Among the cats, left- or right-sided inguinal cryptorchidism were the most common… 
Clinical and Histological Aspects of Cryptorchidism in Dogs and Cats
TLDR
The occurrence of cryptorchidism in Anatolian Shepherd dogs and the Domestic Shorthair cats were first documented in the literature, although, no significant differences were found in the incidence of Cryptorchidistan in both species.
THE OCCURRENCE OF BILATERAL CRYPTORCHIDISM IN CATS
TLDR
The treatment of choice for cryptorchidism in this case was bilateral castration, mainly due to the fact that the pathology is hereditary.

TLDR
A 21-month-old male castrated domestic short hair cat was presented and laparoscopic-assisted cryptorchidectomy was performed, offering the benefits of minimal invasive surgery, which is still underreported in the veterinary literature.
Is the right testis more affected by cryptorchidism than the left testis? An ultrasonographic approach in dogs of different sizes and breeds.
TLDR
Ultrasound scan proved a valuable diagnosis tool for cryptorchid testes, giving precise localization and parenchymal changes thus leading to a safe clinical treatment.

TLDR

TLDR
A four year old male German shepherd presented with the history of anuria for the past two days and dribbling urine for thePast six months and under general anaesthesia a mid ventral ceiliotomy performed.
A Rare Clinical Case Of Double Scrotum With Ectopic Testicle In a Dog
TLDR
The peculiarity of this case is the presence of two independent scrota, an ectopic testicle and its adnexa passing through the abdominal wall, was not supposed to be due a migration along the typical male gonad path during descent.

TLDR
Thirty-six of the 56 retained testicles were in the inguinal region and only 20 in the abdomen, a difference which was not observed in the earlier work, which may have been due to the criteria for defining the testicles' location on the basis of the method used to remove them.

TLDR
High incidence of cryptorchidism in this colony provided good evidence for hereditary nature of the condition in the Miniature Schnauzer dog.

TLDR
The dog should be an excellent model system to further investigate the causes of human cryptorchism and inguinal hernia with testis neoplasms, because the anatomical development of the genital tract, testis descent, and tunic relationships in dog are very similar to that in man.

TLDR
The feasibility of conducting prospective epidemiologic studies of canine diseases with the assistance of practicing veterinarians is demonstrated and testicular neoplasms that developed did so within the first year of observation are demonstrated.
