Risk of resistance? YES, moderate in:

Resistance of fleas to synthetic pyrethroids is common in many countries, including the USA, and resistance of brown dog ticks (Rhipicephalus sanguineus) has been reported in several places (e.g. the USA, Brazil, Spain, Panama). For this reason efficacy against these parasites may be weaker and protection shorter than expected.

Alternatives to prevent resistance through product rotation:

*F = effective against fleas; T = effective against ticks.

These alternative products may not be available in all countries, or may not be available as collars.

Resistance of fleas and brown dog ticks to carbamates and organophosphates is not uncommon in several countries, including the USA.

VETALITY PROTECT FLEA & TICK COLLAR is an insecticide impregnated collar for dogs from TEVRA containing generic deltamethrin. It is a generic version of SCALIBOR (introduced by INTERVET). It is exactly the same as TEVRAPET PROACT FLEA & TICK COLLAR also from TEVRA.

Deltamethrin is a veteran synthetic pyrethroid insecticide and tickicide introduced in the late 1970s (by ROUSSEL-UCLAF → INTERVET → MERCK AH). It has a broad-spectrum of activity against insects, ticks and mites. Use in dogs is rather modest. Until the 2000s it was very much used against agricultural, domestic and veterinary pests of ruminants. Nowadays usage has declined because numerous pests (e.g. cattle ticks, horn & buffalo flies, houseflies, sheep body lice, fleas, mosquitoes, cockroaches, etc.) have developed resistance to most synthetic pyrethroids (incl. deltamethrin).
The label claim of 6 months protection is substantially longer than for most alternative flea-control products (spot-ons, tablets, etc), but may not always be achieved due to resistance of brown dog ticks (Rhipicephalus sanguineus) and/or fleas to synthetic pyrethroids.

Topical products (mainly spot-ons and insecticide-impregnated collars) have some advantages over systemic products (mainly tablets for oral administration and injectables):

  • Most topical products kill or sterilize the parasites before they bite and suck blood on the pet, whereas systemic products kill or sterilize the parasites only after their blood meal.
  • Topical products cannot be vomited.
  • Spot-ons and collars are very convenient to administer.
  • There is a larger choice of topical products.

But topical products have also some disadvantages:

  • Topical products contaminate the pet's hair coat and it is advisable for children and also adults to avoid contact with the pet for several days after treatment.
  • Topical products may not control parasites in some parts of the pet's body (e.g. the ears, below the tail, between the legs, etc.), whereas systemic products reach the blood-sucking parasites through the blood wherever they are.
  • Efficacy of topical products may be reduced or shortened through exposure to dirt, sun, shampooing, washing, rain, baths, etc., whereas efficacy of systemic products is independent from these factors.
