Little research has been done to validate the biomechanical principles of tibial tuberosity advancement (TTA) throughout stance. The present study evaluates the effects of TTA on kinematics of the cranial cruciate (CrCL) deficient stifle during early, middle, and late stance. Cadaveric pelvic limbs were evaluated for the effects of TTA on kinematics under a load equivalent to 30% bodyweight and under the following treatment conditions: intact CrCL, CrCL deficient, TTA-treated, and TTA treated + meniscal release. Electromagnetic tracking sensors were used to determine tibial subluxation and rotation relative to the femur. Transection of the CrCL resulted in significant cranial tibial subluxation during early, middle, and late stance and significant internal rotation during early and middle stance. TTA normalized tibial subluxation in early, middle, and late stance but was unsuccessful in normalizing axial rotation in middle stance. Meniscal release had no effect on cranial/caudal or rotational displacement when performed following TTA.

This thesis attempts to answer the questions "What purposes do family pets and the narratives we tell about them serve in modern American society?" and "What do these stories tell us about what Americans value and about where we locate our ‘value center’?" In Chapter 1, I discuss how Americans define loyalty in our pets now that our animals generally no longer help us work. I conclude that since the shift from agricultural to suburban settings, animals prove their loyalty individually and in human-like ways, rather than as "good" members of their own species, but at the same time because of their "animalness" they also provide us with a small but critical connection to nature. In Chapter 2, I explore how Americans experience spirituality or a "sixth sense" through our pets, especially our cats. These narratives show that many Americans are somehow able to hold diametrically opposed folk beliefs about exactly the same animal: while personal family stories about cats are almost uniformly positive and feature an angelic cat hero,impersonal folktales and legends still persistently characterize cats as evil and demonic. In Chapter 3, I look at how we work out our very American obsession with bigness through telling stories about our dogs. These stories allow us opportunities to talk about the socially inappropriate issue of male body size expectations, by celebrating big dogs and "under"dogs and by ridiculing those with "little dog complex."

Objective: To describe foreign bodies (FBs) in the nasolacrimal sac of dogs, the history, and simple diagnostic and therapeutic approaches. Animals studied Fourteen dogs of different breeds, ages, and sexes were presented with unilateral dacryocystitis and had been treated without success for over 1–8 months. Procedures: Patient history, including prior treatment, was obtained from medical records. Slit-lamp examination was performed in all cases (SL 17, Kowa Company Ltd.). Jones tests 1 and/or 2 were performed in 13/14 cases. Dacryocystotomy was initiated with an incision into one canaliculus until the lacrimal sac was exposed and could be explored. After extracting the FB from the nasolacrimal sac, the surgical wound and canaliculus were left open. Aftercare included the administration of antibiotic eye drops with or without dexamethasone and systemic analgesia. Results: All 14 dogs were mesocephalic. Four of them were Dachshunds. Dacryocystotomy revealed plant-related FBs in all cases. The purulent discharge disappeared immediately after removal and did not recur during follow-up. Conclusions: A simple dacryocystotomy is recommended for dogs with a strong suspicion of a foreign body in the lacrimal drainage system. Dacryocystorhinography appears to be an optional tool in these cases.

Dirofilaria immitis, commonly known as dog heartworm, is a dangerous filarial nematode that is transmitted by a mosquito vector. Although this parasite is historically localized to regions closer to the equator, the last few decades have experienced an increase in the amount of dog heartworm cases in Northern California, most notably in Lake and San Joaquin Counties. The primary vector of D. immitis in Northern California is Aedes sierrensis, but it is not prevalent enough in some counties to explain the increase in infections. Because of this, more prevalent and abundant species should be assessed for their ability to transmit heartworm. Culex pipiens complex (wild) and Culiseta incidens (laboratory-raised colonies) were chosen as potential vectors during this study due to their ability to meet several key vector criteria, their relative abundance in the areas of interest, and the fact that they habitually take bloodmeals from domestic dogs. Additionally, Ae. sierrensis colonies were used in this study, based on previous knowledge that they are highly competent vectors. Female mosquitoes were infected with 2.5, 5, or 10 mff/ul of D. immitis-infected blood, and decapitated at 15, 18, and 21 days post-infection. Mosquitoes were subsequently tested via qPCR for the presence and relative quantification of D. immitis DNA. We found that Ae. sierrensis and Cx. pipiens complex were both able to support the development of D. immitis to its infective stage, while Cs. incidens was not a competent vector. We also concluded that including a standard curve of known amounts of D. immitis larvae makes it possible to approximate the intensity of the infection in the mosquito. The identification of these important vectors, and the ability to assess infection intensity, may be helpful in the continued vector control efforts in Northern California and beyond.

Service dogs are becoming an integral part of our society. Consequently, there is a need for research that explores how Canada should proceed with the development and implementation of appropriate laws and policies that will ensure the proper use and equal integration of service dogs. Before this can take place, the terminology used within the field must be clarified, as society continues to move toward a more expanded definition of service dog, and public access challenges continue to impact the lives of persons with disabilities. The goal of this autoethnographical research study was to determine what service dog handlers, particularly ‘owner-trainers,’ feel constitutes a ‘service dog’ in Canada. When researchers conduct investigations on topics related to the lives of persons with disabilities, their research typically takes the form of disabled individuals being studied and not being directly involved within the research. Therefore, this project sought to directly involve persons with disabilities, while also attempting to avoid the possibility of censorship or silence. Through the use of statements from social media, this project captured the lived experiences without worrying about participants changing them to fit within society’s expectations. Society is not structured to be accessible for all, so when ‘accommodations’ are made, it is ‘expected’ that persons with disabilities will show gratitude and not voice their true feelings. Through the use of autoethnography, I shared my experiences, as a service dog raiser, trainer and handler, and provided a glimpse into the lives of other service dog handlers as they participate within their communities. In doing this, I hope the findings of my project will offer an important perspective to the discussion surrounding what constitutes a ‘service dog’ in Canada. / Thesis / Master of Arts (MA)
