I have a 2+ year old NHR what seems to either be egg bound or something else-not sure what else it would be. She is eating and drinking and pooping, but seems a little slow in regards to walking. Her belly near her vent area seems swollen a little and hard. I gave her a bath in warm water and message her belly. I also checked her vent area with my finger and do not feel an egg. in the past she has given me rubber eggs... I have called all the area vets and no one can take her! not even Tufts, which is one of the best vets in all of New England. what can i do to help her? what can this be? any help would be great!
