Wow, 49 lbs., that's a lot even for a corgi appetite. You may find his energy level increases if you can get his weight down, but he may not appreciate being starved. The heat may be part of it -- I don't tolerate heat well myself -- it hit 103 F. in Seattle this summer, knocking 2-3 degrees off the all-time record -- and I just wilted, it was one long siesta. There's a lot of discussion on MyCorgi about heat; most advise against haircuts, arguing that the fur insulates against heat. I can say that ours visibly wilt in summer sun above timberline where they start seeking shade behind rocks; then I look for snow and make a "corgicicle", which they love. Idea? Keep those freezer gel bricks in your freezer and throw one into the crate on a hot day?

We try to restrict their diet pretty carefully/drastically, which is difficult since as you know they'll eat ANYTHING with scant regard to edibility (the catbox is fenced-off). Al is currently harvesting all the fallen plums.
As a refined connoisseur of dog shit, my considered opinion is that raw meat poop unadulterated with kibble is the best: no stink, no smear, no muss, no fuss. We save the Wellness kibble for treats, mostly.

Re. Siri's death in a choking accident, she was a gulper who INHALED her food. Any morsel of food dropped in the kitchen would never even hit the floor, even if Siri was asleep on the living room couch when it dropped.
She lived on whole raw chicken drumsticks, chicken wings, chicken necks for many years. Glurp... they'd just disappear. So maybe we got used to this, and although there may have been a warning thought that the turkey neck was a little large.
That was so terrible.

Parenthetically, I can say that neither of us reacted well to the emergency. In First Aid training, they teach that Step 1 is, "Recognize that you have to act". I was in the basement; instead of screaming "Help! Now! Bloody Hell!", my wife started telling me through the floor that she though Siri was in distress, I didn't hear this clearly; when I finally came up (already to late), I was in the familiar "Nothing Bad Ever Happens to Me" mode, whern I should've been thinking< "A, B, C":
Airway?
Breathing?
Circulation?
I reacted similarly when we were first on the scene of a serious injury car accident.
There was nothing we could've done in any case; the vet couldn't even get it out and she was dead before we left for the ER.

We feed raw meat, but get it ground and frozen and delivered from a great local Seattle company (Darwin's, "It's a Natural Selection", ha-ha). I don't even want to know what we pay for this. There was never any problem with the chicken wings and legs -- uncooked bones don't splinter -- but those pointy little bones sure make me nervous. I would be afraid of the sanitation state of raw chicken/beef meat from crowded factory-farm conditions -- we have no USFDA anymore, really. Salmonella, E. coli 0157:H7. The stuff we buy is allegedly human-grade, but that doesn't mean much, so we try to rigidly segregate the raw meat tools and prep area from human food prep areas; we even have a dedicated knife to open the freezer bags.
The raw meat cleared up Siri's skin problems. We give just a tiny bit of kibble (~6 pellets); this softens the turds a bit. Too much kibble gives dogbreath and stinky soft poops -- we're city people and have to pick them up.
Hope this is useful.

I am so glad to hear that there are other "Jumbo Shrimp" out there. Twinkie is a fluff that easily weighs 37lbs. We live in Georgia and although I know Twinkie gets hot I don't think its worse for her than our other dogs. I think her coat might even "breathe" better. I do keep her tummy shaved so she can enjoy laying on the tile while inside. I'd also like to add that Corky is one of the best cogi names I have heard. I also think Archie is a real cute boy.

Welcome!

Welcome to the group, so glad you could join us!

Welcome! Your corgis are adorable.
