I see Davey's AMPS this morning was down quite substantially.

...
... but extra care is needed now -
especially if Davey is declining the very high carb, dry food he has been eating up till now. Here's an example of why the worry:
The above is a snapshot of Saoirse's BG readings for before, during and after her transition from dry high-carb to wet low-carb food. She was on Caninsulin and her BG readings were taken using a pet meter, as is the case currently with Davey. (NB: I have non-standard colour coding in Saoirse's spreadsheet. Key is at top of snapshot.)
On 13.07.14 Saoirse would not eat any more dry food. Look at what happened to her BG between PMPS and PM+3 - a drop of 13 points!
The above shows just how fast and how far BG levels can fall with removal of high carb food from the diet (especially with removal of high carb dry food). Also look at how quickly and how often it was necessary to
reduce the insulin dose. (Had to feel my way with this at the time because I was a novice caregiver, had minimal useful input from the vet available at the time (our main vet was away for a few days, and didn't know how even a small dose of Caninsulin could yank down high preshot BGs into very low numbers mid-cycle. I was only able to keep Saoirse safe because I was home testing throughout the transition and reducing her dose based on her data then and for several days following.)
(Note: The all-yellow cycle on AM of 20.07.14 was due to duff insulin: it had been like a
sauna in the flat during the night, my fridge was useless and the insulin overheated. A fresh vial for the PM cycle showed Saoirse returning to lower numbers again on only a tiny dose of Caninsulin.)
Suggestions:
1. Contact your vet straight away and agree a
significant dose reduction (possibly even a small token dose) to give in the event where you are low on test strips.
2. It was a very smart move getting the human meter. With Davey not eating the dry, high carb food and the high dose of Caninsulin this is a time when you really, really need to home test.
3. Get a supply of high carb, wet food to see if Davey will eat that instead of the high carb dry. (Contingency.
@MrWorfMen's Mom - any suggested Canadian foods?)
4. Continue monitoring ketones closely (especially with a reduced dose).
Last night he was following me around like crazy looking for wet food so I have to admit I gave him a half a can more than I usually would and in turn he didn't eat any dry food last night. He had dry food in his bowl but as usual just didn't want it. I'm sure this is probably the big factor so I will need to be careful.
I just used my last [test strip] this morning and should have received them today but (just my luck) when I go to track the shipment it's not arriving until Monday due to a weather delay. I can't make changes over the weekend with no strips
Now that it's unpredictable whether Davey will eat any of the dry high-carb food, any time you're not around to monitor I suggest you make sure Davey has food available at all times - higher carb wet if necessary - and possibly reduce the dose of Caninsulin.
There is such a big difference in the preshot BG today compared to the previous cycles that extra caution is vital. With less hyperglycaemia due to the reduction in amount of dry food eaten Davey may also start becoming more responsive to insulin generally.
Safety tip: If Davey is running in the lower range mid-cycle but the preshot is high, follow the nadir values when making dosing decisions, not the preshot. (Even small doses of Caninsulin can really yank unexpectedly high PS BGs right back down to low numbers again. Also keep a close watch on his clinical signs and test him if you see any unusual behaviour - especially if he starts looking for food OR if he seems lethargic.
