An update; According to the orthopedian consulted this kind of injury is treated whit rest and NSAID. If the tendons would have been cut off surgery should be the choise of treatment, but in this case the dog has run on hard, rough, icy surface and the tendons have been badly streched/ torn and surgery isn´t usally successfull. The dog will not have any career in any running- or agilitycompetitions, but there are good possibilities that she will recover and can live a normal doglife. I really hope that this will be the case for her. At the moment (a week after injury) she is limbing less but still choose to not bear weight on the injured foot all the time.
