Dysplasia is an ill-formation of the bone joints, most commonly observed at the connections between the hip bone and the rear limbs, case in which it is known as Hip Dysplasia. It may affect both males and females of any breed, especially the big-sized and fast-growing ones. Hip and elbow dysplasia may harm only one of the joints, but they normally affect both. That disease is transmitted hereditarily and is strongly influenced by the handling and by the environment. At Canil Interagro, dysplasia reports are issued for EVERY labrador involved in reproduction, who MUST be examined BEFORE mating, but ONLY AFTER completing 12 months old. The checking is made through radiography and to take this "photograph" the animals must be tranquilized, as they are put in an unusual position and the slightest movement may lead to some distortion and, thus, to wrong diagnosis. For a successful exam, it is fundamental that the animal be in the right position and absolutely still. When taking the dog to be examined, don’t forget to bring the original pedigree, and there are two reasons why that is so important: the veterinarian must be able to "print" on the animal the pedigree identification number through a tattoo on the ear or a microchip on the neck; therefore, the radiography will contain the animal’s identification and name as well as the date of examination. Not all veterinarians are experienced or qualified enough to carry out the exams but you can find some indications on Links
At every stud dog’s profile you may find important information about the dysplasia control made by Interagro. As an example, see Edward’s presentation:

indicates where the dysplasia radiography was taken; it is a specialized diagnosis center in São Paulo in which fully qualified professionals have their work praised all throughout the dog breeding world. BVA stands for British Veterinary Association, institution that also receives these radiographs and carries out evaluation. The participation of this British association is another security measure, as the majority of Interagro’s dogs was imported from that country. With those "scores", the BVA draws updated panoramas and monitors the evolution and/or involution of the dysplasia in several breeds. Presenting these international parameters also makes it easier for foreigners to understand and avoid confusion about the abbreviations used in Brazil.The code used above by the BVA to show the results is "05:03". The symbol that follows, HD- (standing for Hip Dysplasia) is used in Brazil. What does each of them mean? The BVA’s numbers are the "scores", or the grades given to each of the joints, always the left one first, followed by the right one. The lower the numbers are, the healthier the dog reported. In order to evaluate how close the dog is to the accepted standards for the breed, the "scores" are summed up. In our example, the summing results 8. The average for the Labrador breed, reported by the BVA in 1998, is 16,4 for the summing of the "scores".
The BVA analyses each joint separately and the exams will only be finalized after being submitted also to an anatomist, a radiologist and a geneticist. They evaluate aspects normally bypassed in Brazil, such as the fitting of the femoral head, sub luxation, and the femoral neck.
The codes in use in Brazil are read as follows:

A

B

Good for reproduction HD+
C
Still accepted Good for reproduction HD++
D
Moderate to mild Not Good for reproduction HD+++
E
Severe to serious Not Good for reproduction Also in the exams made in Brazil, grades are given to each of the joints, but it has become usual to present only the worst evaluation to build up the diagnosis. Therefore, an animal whose evaluation has resulted HD – at one side, and HD +/- at the other, has a Normal side and the other Almost Normal. The presentation of its degree of dysplasia is thus classified as HD +/-.
For example: Gr. Ch. Pan. Int. Interagro Skipper Wolf’s Hunter is HD – at the left side and HD +/- at the right. He is presented as HD +/-. His BVA is 08:08.
Frequent brucellosis examsBrucellosis is an illness transmitted by bacteria which dogs are probably the ultimate hosts for. The principal symptoms are abortion with no signals, failure at the earliest stage of pregnancy that leads to ill-formed or stillborn puppies. It may infect males and females through coitus, exposition to any body fluids (saliva, semen, urine, etc) or ingestion of contaminated material. All stud dogs at Canil Interagro are examined every 6 months– AT LEAST. Some qualified veterinarian collects the blood and conveys it to the laboratories; some of the institutes of diagnosis, such as IVI and Provet, collect the material themselves. The completion time for the results may take 5 to 8 days. See indications of clinical institutions on Links.
Semen AnalysisThey are also frequently carried out in order to evaluate the quality of the semen, analysing the strength, motility and concentration of spermatozoon. The Stud dogs who have been over 60 days without mating are submitted to sperm analysis, as well as those who haven’t been parent of any brood for the same period, particularly before mating again.
