Crawford is an 18 year old dog with a collapsing trachea. He can greatly benefit from the use of a concentrator.
Please notify if you know of one that can be purchased second hand at a reasonable price.
These are often used when humans have a home oxygen service as it can take room air and concentrate the oxygen in it for those who need oxygen for respiratory issues. The same equipment can be used for an animal.
Crawford’s mom and dad are good friends of mine. Please spread the word.
