Spaniels shed, Goofy is a Cocker, and you will have a lot of coat care to be prepared for. Along with ear care, which many spaniels have issues with, be aware of that, and do your research.

From fall through early spring I keep Goofy in a full coat, but for ease in the summer and because her coat is so hot for me to brush we keep her in a puppy clip. She goes to the groomer about once a month for regular baths (they have a "smell" if not kept up) and Goofy has by nature a oilier coat than her sibs did. Her nails and ears are kept trimmed ,(inside ear care is a must) and her groomer pulls the inside ear hair, total cost each month for bath blow trims and coat care? 40.00+tip so 65.00.

You can learn to do much of it yourself, I prefer not to is all.
You are on the right path, by researching and showing your reliability with Sassy.

Hugs
