How to block bird feed stations from Jack Russell?

why not try and put a kind of net to catch the spills, especially where the feeder is kept. Hope this is possible. At least it will limit the spills:)

my thought was to put a screen under your bird feeder

Although it is very kind of you to feed the birds, the health of your dog is more important right now, and I would remove all bird feeders until he is healthy. In the mean time you can research other ways to feed the birds without hurting your dog.

Do you have enough space where you can put some 4" or 6" cattle fence around the feeder. It will keep him out and you can still enjoy the birds. This is what I've done in my backyard because of the neighborhood cats. It doesn't spoil your view either. I have a vine running on mine.

Put your fat balls, I assume it is some kind of suet, in a feeder that would contain them and has holes the birds can peck them through. I use these little peanut butter ones you can purchase and there are metal mesh feeders that you use with them. I keep my suet blocks in suet holders they peck through also. I keep my feeders in the side yard where the dogs can't get to them or I would never have any birds at the feeders.

Purchase an exercice pen from a pet supply company such as Doctors Foster and Smith and put it around the area. http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=34802

I recommend the 30" tall one. This one has a drop pin that you can take out and open up the pen to put around the area and then put the pin back in. If he moves it, you can get some tent stakes to secure it to the ground.

Thanks to everyone for your suggestions. I think it may have to be a combination of all of them. What I call my bird sanctuary is a very large area with over 50 different bird feeders and 3 large bird tables. I have been able to attract very many unusual birds including last July an American Blackheaded Grosbeak The RSPB confirmed from this photo that there's only ever been 1 or 2 of them recorded in UK & certainly non in NE Scotland where I am. He stayed for 3 days but disappeared and hasn't been seen again. He must've been exhausted after that 3000 mile flight across the Atlantic😂 I really want to continue to feed the birds but agree with the lady who said my beloved JRT Angus's health has to come first.

Thanks

Have you tried and squirrel type deterrents?

Hand the feeder off a large S hook. Not enough seeds hit the ground where he could benefit. Hang from the gutters, a tree or I had a hanger for bird feeders.

Is there something like cayenne pepper that you could add to the fat balls that would taste bad to the dog, squirrels, etc., but not the birds? Otherwise, I'd limit the suet to one area and put some sort of tray/screen under it to prevent it from landing on the ground.

You could put your suet feeders on a pole with a baffle, placed upside down to catch the chunks that fall, then the birds will still have access and your boy won't. If he is eating seed hulls, they are simply adding fiber to his diet, not calories. If I may ask, what are you feeding him? A small dog, on a premium diet, should only be getting 1/4 to 1/2 cup of dry kibble, twice daily, depending on his activity level. I honestly don't think a chunk of suet here and there would keep him from losing weight. There is no need to stop feeding your birds, not only do they bring you joy (which is hard to come by in this day and age) they are keeping insects at bay. The birds now depend on you and you on them.
