 There are several breed traits which may cause concern as health issues . They include skull issues such as an open fontanelle , where in young dogs there is a soft spot in the skull ; it is common in dogs under a year old . A complication from that condition is hydrocephalus , also known as water on the brain . This condition may cause neurological symptoms that require the dog to be euthanised . Fused toes , where two or more of the dog 's toes are fused together , may seem to be a health issue but this breed trait is not a cause for concern .
