“…It is widely recognized that aspects such as genetics, sex, body size and weight, general health, and nutritional status can affect the time of dental eruption in dogs as well as humans or other animals (Barton, 1939; Colyer, 1990; Sahin et al, 2008; Silver, 1969). The mechanism of dental eruption is mainly the result of remodelling (bone resorption and formation) of the alveolar bone at the occlusal and apical site of the dental follicle, genetically regulated by the production of signal molecules such as growth‐related hormones and mediators such as epidermal growth factors (EGF), transforming growth factor beta (TGF‐β), interleukin‐1 (IL‐1a), colony‐stimulating factor‐1 (CSF‐1) and eicosanoids1 (Marks et al, 1995; Marks & Schroeder, 1996; Tanaka et al, 2004; Wise et al, 2002), in response to external signals, including pressure on the bone and crowns of erupting teeth and tension in soft tissues at apical sites (Sarrafpour et al, 2013; Wise & King, 2008). Many of these factors and genes involved in their regulation also play a role in physiological growth, which might explain the influence of breed size.…”

Breeding and trading dogs are subject to strict regulation, both to safeguard animal welfare and public health. These legal requirements may be tailored to specific developmental stages and age categories of the dog. For instance, puppies under 8 weeks of age may not be transported within the EU without their mothers (Council Regulation [EC] N° 1/2005). Puppies traded across borders may currently not be under 15 weeks of age due to the rabies vaccination protocol (Annex III to Regulation [EU] N° 576/2013 and Directive 92/65/EEC). A swift and reliable assessment of age is therefore a prerequisite to verify that legal age requirements are met (Modina

Background: When complete recovery of tongue function following tumor excision is desired, reestablishment of the complex movements of the tongue is necessary. However, currently available methods for recovery of tongue function, such as flap surgery or prosthesis insertion, are inadequate. In the current study, we investigated the effects of transplantations of tongue allografts. Methods: Hemi-tongue allotransplantation procedures were performed with 8 pairs of sex-blind and unrelated beagle dogs. In each donor, the right side of the tongue, including the lingual and hypoglossal nerves, extrinsic muscles of the tongue, mucous membrane of the oral floor, lingual artery, and vein were exposed. A vascularized transplantation method was used with manual anastomosis of the blood vessels and nerves. Results: Survival of the grafted tongue was only noted in 1 dog that died 5 days after transplantation. We suspected that the death was due to nutritional deficiency or dehydration, rather than hyperacute rejection of the transplant or technical failure of the microsurgical anastomosis. The grafted tongue was partially connected to the side of the recipient tongue, and lymphocyte infiltration was observed in this dog. Conclusions: Postoperative management is difficult in dogs. Even if tongue allograft including nerves and extrinsic muscles is performed, it seems to take a long time before the tongue recovers its functions. Furthermore, expansive tongue allograft was too invasive a treatment for animals. If we want to adapt this procedure to humans, the first trial in a human will be done without animal experiments, as was the case with face transplantations.
